Thanks for making a vid that's 10 times better than the one walpro puts out. I have to confess I thought I had the wrong kit but you quickly pointed that the diaphragm fuses with the gasket and I realized what I was looking at. Tiller runs fine now.

Great video. I much appreciate the effort and detail. I have an exploded diagram of the WYL carb, but nothing like seeing exactly where the springs are, or should be, and seeing how to deal with the needle valve. Helped me rebuild a WYL on a Honda Harmony tiller with a lot less anxiety. Even better: I did not have to remove the throttle stop; I was able to slip the line off the throttle lever by just moving the throttle lever down.

cool trick with the flashlight!

Thanks to your video, I got my leaf blower back up and running today! In my case, the metering lever cross pin or shaft that came with the rebuild kit must have been a little different than the original, because when I tightened the retaining screw down, my metering pin and lever wouldn't spring up. I just used the new pointed pin with the old shaft and fork, or whatever you call it. Like the one in your video, both old diaphragms were way less flexible than the new ones. The symptoms that led to this started year or two ago, where my engine would bog down occasionally, and loosening the fuel cap seemed to help. This year, nothing helped until I rebuilt the carburetor. Thanks for your excellent step by step guide!

I have worked on similar small carbs for 20 years off and on and this video taught me 3 new things I had no idea about. Awesome Video!

Sounds like a wind storm outside! Good job.

Thank you for posting this video, found it incredibly helpful! You may want to change the title to "Honda GX31 carburetor overhaul" so people can find it.

Great video. Really knows his stuff. I found my problem in the small filter screen which was totally clogged ... don't ignore this vital part when you rebuild your carburetor.

A fine job indeed sir! I love rebuilding 2 and 4 stroke carburetors. Because my hands are so big its almost like a joke! Lol!!

7:42 Ah...... so that's where the bloody spring is meant to go! Cheers & Merry XMAS m8.

Very professional thanks looks very similar to my GX35 carb which I'm about to strip down, thanks

That was very well done very real explained nice and slow

Good job I didn't realize the repercussion of carb cleaner in the little carbs I'm guilty of over cleaning w it Lesson learned forgotten tomorrow lol

Excellent video, very well explained, keep up on the great videos. I would like to see you rebuild one of those small motors.

Actually there is a smal flat headed adjustment screw where the gas wire is located, it's inside the center hole of the plastik. Adjusts the fuel ratio.

Thanks to your video, you probably saved me from countless wasted hours of my life, helped me to not learn 10 more cuss words and several shotgun shells from blowing up Walbro Carburetor. I watched it twice, only the second time with a beer. I took it all apart, which really wasn't that much but I had the confidence from watching your video. Breezed right thru it all. Can't wait to crank it up, can't do it now, its about 2am, ??? on the other hand. hehehe Hey thanks....You Da Man!!!

very helpful. a guy at work let me borrow his tiller with one of these, and when it bogged and wouldn't crank i was scared i'd have to buy a $300 replacement. took it apart, cleaned it up(i think a port was clogged with trash), cranked right up, returned it immediately :P

My issue with this style of carburetor is the throttle ramp that lifts the rotary valve as it turns. It is there to lift the metering pin out of the main nozzle at the throttle is opened thus allowing more fuel flow. As that ramp and plastic pin wears down there will be less lift and the engine will eventually run lean.

Super thank you

Very helpful video, thanks for posting!

Thanks for the video. A question: I lent my Gx31 weedeater out, and premix got ran through it. It now bogs under load. Tried the plug- no go. Could a carb rebuild be in order? Thanks.

Excellent video. Good job.

If you look at the carb at 9:02 and look at the fuel intake hole (where the mesh screen/filter is). That's where the gas goes in from the gas line. Afterwards it goes into the smaller hole directly under it. After that it goes into the slightly bigger hole that is located under and to the left (7:30 a clock). From that hole the gas goes into the slightly smaller hole that is located under and to the right (5 o'clock). What baffles me is that that last hole is covered by a little tab on the black gasket. How does the gas get into that hole if the hole is covered? Put the gasket on and see for yourself, a little tab sticks out and covers that last hole.

Great video. Recently cleaned out my carby after the motor was submerged in a flood. The fuel pump diaphragm spring fell out without me noticing. Noticed the extra on assembly. Where did it come from? Your video showed me where to return it. Thanks.

I also did a test to see if the gas can somehow get through even though the hole is covered. I put the gasket in between the two carb halves and blew air through the fuel intake fitting and it was all sealed up, no air escaped any where. ???

Great Video.

Another excellent video. I believe that is a Walbro WYC rotary style carb. Unlike many such units, WYC's have no accessible hi and low speed screws. Where there would be such screws on other rotary carbs, there are what look like little "bb'.s" blocking access to what may be said adjustment screws. I suppose this to prevent the consumer from making adjustments. Do you know how to remove the bb's so that the adjustment screws (if there are any there) can be accessed?

On the fuel pump spring side of the carburetor body there's a small recess with a square shaped material that has a hole in the center. It can barely be seen at 15:03. You don't mention it in the video and parts diagrams don't mention it. Any idea what it is?

Great help! That's a WYL? Very close to my WYC-27-1. I wonder if the L stands for 'lip' on the air intake? You can buy an aftermarket carb replacement for this on eBay from China for less than $13. I just swapped my Walbro on a Hitachi RB24EAP blower for a RuiXing I had sitting on dead equipment and it works fine.

Thank you very much!

great vid.

I'm Still working on this thing. rebuilt the Carb exactly to your specs. New carb kit, fuel lines, bulb, fuel filter, air filter, adjusted the valves, put in new spark plug, new fuel and still idles ok but BOGS upon acceleration. Today while it was running, I sprayed the black throttle body with the adjustment screw and the engine would instantly die. Throttle body doesn't seem worn out, so I took it all apart again for the 6th time, put all back and still the same. Bogs on acceleration. help?

good vid! Can we see a pic of your ultra sonic cleaner?

thank you my friend can you show me how to do camshoft timing pls thanks

16:00 The metering pump diaphram you installed does not match the old one. the old one has two more holes in it. Did unit run?

Which was why the tines weren't turning, not enough acceleration to turn them. Checked out a friend with same model and his sounds like a Chain Saw. I soaked the carb bodies, blew can air through all the holes and ports. double checked the float level. 61 on the nose. I really hate to buy a new carb because I really want to troubleshoot this one. Any advise?? Thanks ...Ron

Can i use a new exhaust manifold gasket, that i have, for a carb intake gasket, that i need? thanks

Hi small engine shop, i have a GX 35, and people say that if you drill the main jet bigger, it would increase the power, is this true? Will there be any disadvantages? thanks.

would the gas eat it up or what? it's my only ride for now. can i ride it to the parts store?

a odd question but what camera recorder do you use? cheers, like the vid

How do you know which kit to buy? I have the very same carburetor as the one shown. I tried search online with the numbers on it, they are WYL 70A025 any thoughts?

Where do I find the "type code" on the GX31? I found the serial number and another three character number of GD2 but that doesn't seem to match up to any type codes I find on ereplacementparts.com

These are aggravating little buggers, not made for people w/ normal size fingers. You need tweezers to work on them. This is the same carb used on Honda GX25 weed whacker & am having the same high speed problem. Cleaning does not help. They have no way to adjust the high speed mix & very limited means to adjust the idle mix, need a special (unobtanium) tool. Hard to locate a proper service manual or blowup of the carb. Found one for the WY series Walbro carb but it doesn't match my carb or the one shown in this video. Good luck if you are unfortunate to have acquired one of these. And the little metal "ruler" is called a scale in machinist parlance. Video helpful though.

the only thing different for me is I say where in the #$% did it go! lol
