Berryman chemtool -

My pilot is clogged on my Harley. so I ran 15 tanks of premium through it crossing 3 states. had to baby the throttle at stops and traffic the entire time to keep it running. At the end of the ride, it still wouldn't idle. But.. man did my riding skills improve!

I find this solves 90% of peoples real problem. It is why it is front and center on my website. The problem is no one wants to have to take their carburetor apart. This is a good tutorial.

I had a carb recently that would only run on choke and I tried EVERYTHING. The answer, it turned out, was that I was being an idiot and had choke/on and choke/off positions reversed in my head. I was so happy and so irritated at the same time when the realization hit me ) Thought I'd provide a laugh for the rest of y'all.

Im well aware that i have the maturity of a 12 year old but i was not expecting the word 'orifices' while i was taking a big drink of my morning coffee ... so thanks for that.

ANOTHER REASON: Similar symptom, but different cause. The circlip popped off the needle in my Honda FCR carb. So the needle was simply sitting in the fully down position even if I twisted my throttle. It would still idle, but that was all. When I engaged the choke, it brought the "idle" speed up a few hundred RPM (as is normal when you engage the choke). This allowed me enough power to limp out of the bush back to my vehicle. Thankfully it was mostly downhill.

My bike runs with it on or off, idles fine with it off but on take off it spits and sputters and barely lets me shift

Why my 86 fj 1200 would only run on choke. A malfunctioning vent valve in the vapor recovery system caused vacuum in the float bowls so no fuel could go into the jets. Full choke opens a vent to atmosphere in the float bowls so engine would get fuel. It happened on the freeway at night. so I just kept opening the choke everytime the engine would stop running.

Just to be clear you know they have needles specifically made to go through the jets right now not all channels can be cleaned that same way I've seen a few carburetors primarily dirt bikes that have small channels in the actual body for some freaking reason the first one I seen it on was my 2005 or 2006 TTR 125 Yamaha but all of the jets that are removable can be cleaned with these small needles that are sold specifically for this purpose it comes in a little handheld tool with probably 40 different ones and you just find the right one for your jet size and no as long as you do it the proper way which is reversed of the way it actually flows you're not going to damage it at all unless you got metal stuck in it typical dirt and grime all come out perfectly fine unless you have something like metal or possibly sand inside the jet and as long as you're operating your vehicle properly you should not end up with sand or metal in the jet it should only be clogged by gunk created inside of the vehicle itself

Good information but your hand was in view of the camera shot

Torch tip cleaners work.

MathewMcRepair good stuff!!! I've been working on small engines for about 8 months now and I've learned alot because of guys like you and I've combined my knowledge and skills with all the ideas and videos you guys load on KZfaq and till today nothing but SUCCESS!!!! Thanks Dude!!!

Dude, thanks. For how complicated carbs are to a newbie, this is a relatively concise yet informative video. Thanks for educating people on something the majority of people, even with mechanical ability, don't know much about.

Dude that was exactly what happened to my outboard motor.i fixed it after watching you video. I found some stuff clogged up the tiny little hole. I just blow onto it. Then I put in back and fire it up with just one pull. Plus no choke.

Great video.

Hey man thank you for this video. We have searched high and low for a weak and we were ready to buy a new motor. We watched videos that told us to clean the carb but none said to clear the debris from the jets. Much appreciated: MBX10 mini 🏍

I had that problem and I followed your instructions and got my atv running perfectly ...thank you. greetings' from Athens Greece

Thanks for the great vid, was able to get my polaris 400 2 stroke running right again.

Great video, That's exactly what I needed for my lawnmower ! Thank You.

Pretty good- I'll tell you as one who's rebuilt a few Honda carbs: that orifice in the low speed jet is .012", .3 mm in diameter, and the use of an appropriately sized wire is actually the best way to clean it--- the wire won't open it up any, but it'll clean off any lingering debris the solvent/blowout process is unable to remove...
