Finally someone who checks out the whole fuel system there can be other problems besides the pilot jet

Excellent video, clear , concise, straight to the point. Zero babble. And thankfully no background guitar noise. Wish others would watch and learn

We have used the kzfaq.infoUgkxOTeIs0vv4_9B5hsmnLsk9r930uDQLu_Y for probably 30 hours with our camper and it’s been great! The noise level is really only noticeable when running the AC and other appliances like the microwave, hair dryer, or coffee pot. It’s not huge like other ones and it has wheels so even at 90lbs, I can move it!

I watched a lot of videos on carburetors,fixed both of my generators,to lawnmowers and three trimmers and i just learned something new today.

Thank you for your videos on this topic. This one, and the one you made to actually remove the carb off the engine helped me so much. I have used my eu3000 every day for the last 2 years and it hasnt failed me until today. It started surging and would cut off under medium to heavy loads. Thanks again for the tutorial.

Thank you for this great video. Your step by step video made it really easy to fix a lemon of a used generator purchase. After watching your video, I was able to get my generator running like a champ. On behalf of my wife and I, THANK YOU!!!

Great video. I have a fleet of Honda bikes and motors and the most common issue is the idle jet blocked. Your tip on the tank filter is a gem. I'll change all my tank filters now. ! Many thanks.

Glad I watched this video before tearing into my Craftsman (Generac) 3000i. Was absolutely dreading having to "gut it like a fish" in order to get the carb off and clean the main jet and emulsion tube just as I have done on SO many motorcycle carbs. Remembered seeing the plastic idle screw on mine and wondered if I had the same pilot jet underneath. Sure enough! Had it out in a few minutes, and, sure enough IT WAS TOTALLY CLOGGED! Couple minutes later I had it back together, fired it up and runs like new! A BIG thank-you for saving me so much time and needless effort!!

TEPCO CYCLE REPAIR, GREAT VIDEO! I RECENTLY RAN TANK LOW, TOOK MY SMALL SHOP VAC TOP AND SUCKED OUT REMAINING FUEL, TANK DEBRIS AND MINOR RUST. AFTER THAT I SPRAYED BRAKE CLEAN ON PETCOCK FILTER, THEN PUT SHOP VAC TIP RIGHT OVER TO PULL CLEANER OUT. THAT HELPED ALOT! THEN I RAN ENGINE WITH FILTER OFF, AND DID SHORT BURST OF BRAKE CLEAN WITH ENGINE RUNNING, AFTER ENGINE STUMBLE THEN RPM RECOVERY I SHORT BURST AGAIN, I REPEATED THE PROCESS FOR A FEW MINUTES THE SURGE STOPPED. IT RAN GREAT AND SURGED STOPPED WHILE I WAS IN THERE I PUT IN A NEW SPARK PLUG AND OEM PAPER AIR FILTER, RE-OILED FOAM FILTER AS WELL PURRS LIKE A KITTEN! IM NOT SURE HOW OLD THIS HONDA EU300IS BUT I THINK IT IS AN EARLY VERISON DUE TO NOT HAVING THE CHARCOAL FUEL FUME FILTER THAT NEWER ONES HAVE (ACCORDING TO THE INTERNET. IT RUNS LIKE A TOP AND THESE ARE GREAT GENENRATORS! GREAT VIDEO ONCE AGAIN

Been searching youtube for 3 hours it's 2am thank you I am now going to sleep. Can't wait to wake up and try this.

WOW, What a nice surprise. I figured here we go, another goof drilling holes in the panels, air cleaner box or ripping the Charcoal Canister out. You are a great mechanic that knows what he's doing and a great teacher for sure. I have a Predator 3500 and can't believe all the bad advice out there. It's unreal and Harbor Freight along with those depending on their generator to keep warm or run their life support equipment pay the price. I did know about the pilot jet but still learned a couple of good points. Great job and am now Subscribed.

Hey!! Thank you! Your video helped me a TON!! My little jet was plugged. Now my generator runs perfectly!!

We had a surge on our generac generator. We took the carb apart and cleaned it no change. Then we watched your video and we cleaned the pilot jet and it completely fixed the surge!!! Thanks for a great video!!

Fantastic video! Thank you! I just picked up an EU6500 with only 200 hours on it, and it ran great when I bought it last week. I don't know what changed, but when running it today, it starts and idles fine, with and without eco throttle on/off. It also ran well when running 2 space heaters. But running 1 space heater, with or without eco throttle, it was surging. It seems like no load is fine. 1/2 load is fine. But anything in the middle and it surges. I dropped the sediment bowl and it was perfect. Not a spec in it. I removed the carb and the bowl had some black specs in it. No varnish, just some fine specs of dirt. The main jet was frozen in place, to the point that I was starting to round-off the flat-head notch on it. So I left it in the carb, sprayed it with carb clean in and out, and reinstalled. The surging seemed to get a little better, but it's still there and comes and goes. I didn't try the pilot jet and will try that next. I really don't want to have to cut the tab on the air/fuel ratio screw, but I guess that may be next as well. The EU6500 has a very fancy carb with the dual motors on the top. I really don't want to mess with them, or a 100% teardown of the carb. I'll try the pilot jet next.... thanks for the great video!

Great maintenance video, allow me to also point out the little Port for the idle jet that is located just below it and the 3 fine holes on the inside next the tip of the air screw that also gets blocked sometimes 😎

I took my 2000 EUi carb off to clean it, it needed it, the fuel bowl was all gunked up. I ultrasonically cleaned it and put it back together. It starts now but surges. Watching this video gave me a few tips on what to additionally check. Once I check those things and fix any problems I see I think it will be fixed.

Excellent video. I wasn't aware of the in-tank filter and have ordered some. Thanks!

Great video! Another good thing to do is clean the main jet and emulsion tube. With bowl removed use a small slot screwdriver up the tube, unscrew, and jet with emulsion ntube will fall out. Clean and poke all holes with a wire. Also use ethanol fuel treatment and try to not use fuel with ethanol especially if not running it a lot.

Thanks Brother! Well done - especially where you demonstrated a test to assess flow on the fuel filter. I am going to go fix mine right now. Previously - main jet clogged. Fixed that, got function. Now the idle lopes a bit and it does not perform great under full load. ... Going to clean the pin-hole then check the fuel filter. Living the dream.

Excellent presentation! Thank you! :)

Nice job on this one. Very informative.

Brilliant presentation!

I was having surging issues with my rototiller. a Powermate. I took the carb apart and cleaned it, drained the gas tank, etc. Nothing worked until I pulled the pilot jet. I didn't have a pin or needle small enough to pass through, but poking it must've cleaned it out. I put it back together and it runs great. Thanks for the tip!!

2:35 THANKYOU sir ! i got a generator, Honda EG3500 x. GXC 240 honda motor, surges. I redone the carb, thoroughly. Now, with this education, will clean that pilot jet. ...thanks again, from Alberta canada. oh, got a 7 hp Xstream 3100 gen, surges too. Both were sitting for years, in a barn. Will clear that carbs' jet, too. SHALOM, Mr cycle repair.

excellent vid, i have a lot of honda engines and gens, def. learned some fuel issue repairs i didnt know about👍

More in depth coverage of the carb and more likely problem. Super helpful. My petcock did not have the white screen filter . 🤷‍♂️

ELITE. Thanks for the great vid!

Than you sir. The fuel petcock filter is exactly the thing I did not check and doing it now.

Thank you so much! Cleaned the pilot and runs like a predator. Lol

Your suggestion solved my problem in an hour. Thank you so much..!

Thanks for the info, I rebuild and cleaned my carburetor and still had a bit of surge. I ordered the kit you mentioned and will be installing it tomorrow. Thanks again 😀👍

Brilliant tutorial. I think it will solve my problems, but if it doesn´t, I still learned a lot. I will let you know.

Thank you very much Has cost alot of time trying to figure this problem out. MERRY XMAS to you Sir.

Thank you sir! Been fighting with my honda clone and this pilot hole cleaning did the trick!

Thanks so much for this great video. I was about to order separate parts, but got the petcock assembly instead. Pretty sure I can fix my surging issues now when I get the parts. 👏👏👏

8:40 "make sure it dumps for a good amount of time" LOLOL

great info, thank you.....

Awesome information. Thank you

Thank you so much for this video! Awesome!

Top shelf instruction for low functioning generator diy guys.

Wow Excellent job. Thank you. 👌

Excellent tips. Thank you.

Very helpful, thank you.

Thanks for the 5 back from bottom. A easy adjustment fix for me.

Awesome job thanks

Good job xD I always end up adding a in line filter,if setup does not have one or those tank ones I hate & removed,lol.

Great Video!!!!! you covered all the possibilities. And you know how to use a camera.

Excellent Advice! 5 Star.

Awesome vid ! Thanks!!!

Best video on this topic I found ,excellent job explaining and showing, Thank you so much Subscribe for sure 🙂

thank you !

Hi, our generator just started surging like crazy. Randomly, barely anything drawing from it. We’re in wildfire country, they did a power shut off for fire safety . So out of the blue, we needed the generator. My other half isn’t here right now, I’m no mechanic. I’m kind of freaking out with the surging, it’s 10 pm and the power is still shut off. My hubby can’t get here until Thursday, the power is supposed to be turned back on tomorrow night by 7pm 🙏. So I’m going to show him your video, hope that is the only reason it’s surging. I’m just praying it stays on all night, daytime not so bad. But night time not so good, especially when you live in the boonies. I doubt you’ll read this tonight, so all I can do is ride it out. I just hope nothing bad happens overnight, or hurts the engine in any way 🙏. Thank you for making this video, I’ll be very curious to see if it fixes the surging. 😊

Mine starts extremely hard in the cold weather. After that, like a Swiss watch. Changed carburetor with a genuine Honda part. Replaced air filter, cleaned spart arrester.

Appreciate ya buddy, thanks

Gray video bro thank you.

Another potential cause is an air leak between the carb and the engine. I had this happen on a new Generac PM2200i. When I looked at the intake gasket, it was obvious that part of it had not been compressed. I applied a thin layer of Permatex gasket maker to the gasket, re-installed the carb and torqued it down and it runs great now.

Adjusting the idle screw helps a lot too with a new carburator.

Great tips!! Thanks

Thanks you. Very helpful.

Dont bogart that filter lol, thanks for helping with my genny

Awesome. Thank you. Its fine gents like you that confirm I am an ignoramus. THANK YOU!

It’s my snow blower that’s surging. Thanks 👍🇨🇦

exelent!!!

This info is golden ....

Just put a new carb on got surge and doesn't want to run with out the choke it was a freebie that sat with old feul for a long time would bet my problem is the in tank feul filter because i tried to just drain the tank through it and barely got fuel so i just pulled the pitcock and drained it but dint clean the filter before reinstalling it so thanks for making me think about it .lol....

Thank you for the info

Excellent video.... thanks!

Fantastic! Can you show a detail of the throttle motor connection? I took mine apart and notice there is play between the stepper motor and the plastic plate on the throttle shaft. Seems like that would allow surging. My throttle does not snap closed..should it? Perhaps I'm missing a spring.

This may have been mentioned before but if you own a Honda 6500eu you must have your battery door on or it will surge. I was chasing the surge until I put the door on and instantly started to run correctly. The second cause would be as this video is doing.

Great Video, thank you!!!

Does all small engine Honda's have the fuel tank filter? I have the Honda GX200 on a Simpson power washer. Thank you, John

Awesome! Thank You.

thank you

Thank you!

Thanks for this 👍

Awesome video. Didn’t fix mine but it was a good try. I think mine is an electrical problem. Any experience on that?

Excellent thanks!!!!

My predator 3500 is doing this right out of the box. 1st tank of gas. I find it hard to believe I need to rebuild the carb but I guess I will.

great video

Thumbs down? Best one I've seen

All Good Instructions Man! Yep!

Awesome ThankYou

I have a Predator 3500 and have had it for about 4 plus years so far. I am having a problem right now with mine. When I go to turn it off it keeps wanting to run and chug, and like it's dying but just won't shut off until all the gas in the carb runs out. Any advice?

I have a different style Honda carb. It is factory sealed, but still has a screw opening to the idle jet area. The carb I have is surging, while engine is running. I put carb on carb cleaner for over 12 hours to bot soften and loosen up any buildup inside the vents and center tube. I then both inserted a small wire down through the idle jet opening, and the wire went the jet hole for a length of over a inch, very freely. I put pressurized carb cleaner through the screw opening, and it comes ot inside the carb's venture area ( so that small vent is free and clear of any dirt blockage. Main fuel flow tube is like new, and clean (even all of it's small holes. Main jet is clean as a whistle, and jet hole is wide open. Now I have cleaned many a carb over the years, and never had trouble like this carb has. I even inserted a stiff nylon brush into the main fuel tube, right up to where it comes out into the venture. Everything is clean as anyone can get this carb. I have repeated this process 4 times now, and still I have surging, while engine is running. It seems as if the idle hole in the main fuel flow tube in the center of the carb is plugged, because the idle section doesn't seem to be getting any fuel through it, and this is causing the engine to surge while running. Is there any way I can open-up that vent hole in the main center tube to allow fuel to pass through once again? It's either that, or I need to buy a new carb. The issue seems to be, half way up the inside of the main center tube. I ordered a set of brass fiber bushes, that will fit into that main tube to see if I can free up that area, and allow the fuel to flow to the idle area. Any suggestions on how I can get the fuel to the idle jet, and beyond on this carb?

Thank you

Surging = Fuel Starvation, especially with less than half tank of fuel. A generator runs at high speeds all the time requiring the highest of volume of fuel in the line at all times. Generators are designed to be low profile and an inherent flaw is that the fuel tank is (TOO LOW) just slightly above the carb fuel inlet for gravity feed through a hose. At high speeds and especially with little fuel in the tank causes a weak flow to the fuel inlet causing starvation/surging. SOLUTION: I have a Honda GX-390 and have discovered that by raising the entire fuel tank by 8" gave me MUCH better fuel flow down to the carb and the surging went away even with almost no fuel left in the tank. You can definitely see the difference (before and after) with a see-thru clear fuel filter which should always be at least 1/2 full during operation on a high speed motor/generator. Another mistake I made was storing Ethanol fuel for more than one season in my shed. The stuff goes bad and causes havoc on small engines. Periodically check the color of the stored fuel in a glass jar. It should be clear. If it is golden/urine colored, DONT USE IT in a small engine.. Car engines don't seem to have a problem with the aged fuel. I had about 20 gallons of yellow colored fuel and added a few gallons at a time to an almost full tank of gas in my car and it burned it with no problem.

Great video. Does the eu2000i have fuel filter also?

I more question. I have to choke eu3000i even when engine is warm/hot. Is that normal? Push choke in second it starts. Runs fine.Thanks from Dennis

Great video. I have about 6700 hours on my EU3000IS (4 years old, CARB model) . About 1200 hours ago, it started running a little rough when ECO mode was off. But, during the winter, I never run the AC, so it stayed on ECO. About 300 hours ago, it really started getting rough. I previously cleaned the carburetor, but decided it may just be getting old. Purchased a new one, adjusted the valves, oil, air filter, spark arrestor. It seems to run a little better when I adjust the idle screw at one speed, but as soon as the load changes, it gets rough again. Now even at idle in ECO, it's running rough. Surges a lot. Anyways, I guess I should try the tank filter. Do you just unscrew from under the tank, or does it just pull out? I don't want to break it... Thanks again. Do you have a patreon or PayPal? I'm curious if it's just at the end of its life and the internals need to be replaced..

I just bought an EU2000I and it was not wanting to take a full load unless the choke was on. I cleaned the carb twice including the top jet and it will only run correctly with the choke half way on. It idles fine but is way lean at full throttle. I was able to get my money back but what is going on. Do these thing have a fuel pump of some sort. Float bowl appears to be full of fuel. It will run all day with the choke half on but it should run without it.

Cleaned out the pilot jet as well as Sonic cleaning all carb parts. Still surging, though not as bad. As far as the mixture screw? What's the advantage of breaking off the tab to make it turn a full turn as opposed to just ¼ turn as it's intended ..... ESPECIALLY considering some genset carbs have no mixture screw adjustment at all - just a plug. I have 2 carbs for our Honda eu6500is. One came plugged (not adjustable) & the other is ¼ turn adjustable. But since some are obviously not intended to be adjusted, how crucial could cleaning out that port really be. I could remove the permanent plug if it were to really help.

I have brand new honda 2200i. Been recalled, ran rough in economy mode before it was in shop,now slightly worse. Runs smoothly at half choke however. Hard to imagine anything clogged, can you suggest an adjustment? Thanks for the great video!

Hi, nice fix, btw is overload alarm on when it surges? Mine does, i dont know if the fuel problem or electrical. Goin to check it out in the morning. Thank you.

Very good video and nice explanation. I have predator 4000 and my problem is that it starts and runs fine on choke but when I slide it to run it shuts off. On choke I can run some tools that don't put too much load on it but If I put heavier load on it it will shut off too. Feels like fuel problem, can you help?

I had to take top fuel indicator off to fix float inside but when I screwed down indicator back on it seems to leak when moving around with full tank. Any recommendations on stopping gas from coming out around edges of the indicator?

Where did you get the filter tube that goes inside the fuel tank? I can not find one for mine

I have an unrelated question to this video. I just replaced the gas tank on my generator. When I filled it full of gas, all of the gas drained out of the upper carb drain hose. Do you know why this would be? I don't see an adjustment screw.

Is that pilot on walbro or nikki carbs for riding mowers?

Are the engines commercial/industrial grade is that why they are better than champion, generac, or Wan

What if the motor surges under no load but runs better (still not great) under load? Older B&S Generac generator.
