Vinnie 7 #26 Posted January 25, 2024 Yesterday I resolved the engine hunting problem by taking the top of the carburetor off and spraying gum out into jets and also compressed air. I just used it today and it started hunting again. I just brought this tractor so I think the gas was bad so I did my best to pump it out and replace it. I was thinking of getting a new gas filter and doing the same thing taking just the top off with the carburetor and compressor. Share this post Link to post Share on other sites

Check for any corrosion or scale in the bowl section, do a new fuel filter, gently blow out the lines. Share this post Link to post Share on other sites

GWNORTH 7 #31 Posted January 25 I followed CODY and LYNNMOR's giudance as mentioned earlier in this post. Removed Carb top (after removing choke cable and muffler shield). Lifted out floats and needle . Removed everything that was removeable, including the idle jet and cleaned everything. I used a piece of 18 gauge copper wire to get into the little nooks and holes. Flushed everything with Carb cleaner and buttoned it all up. A couple of hours invested, and it runs like a top. It won't let me add the video right now of it running , smooth as silk. Says I can only upload 3.97 MB. Share this post Link to post Share on other sites

GWNORTH 7 #33 Posted January 25 I didn't know exactly what the "fix" was, but I think RED-Z06 is spot on, about the brass pilot jet.... I pulled that and ran a few strands of wire through the length of it, then poked wire through the holes in the side of the jet. There was a very slight blockage near the tip, which came out after poking it a bit and blasting carb cleaner through it. I did go ahead and clean up everything else that I could get to. Thanks to the wheelhorse experts, I'm back in the seat. Share this post Link to post Share on other sites

Thanks to the wheelhorse experts, I'm back in the seat. That tiny little hole in the pilot jet is so easy to clog, makes them run with a bad surge, had one that it would reclog a few times a year until i put the carb through a sonic cleaner, waited until i could commit to doing the valve lash, and reseal the intake while i had the carb off Share this post Link to post Share on other sites
GWNORTH 7 #35 Posted January 25 (edited) Right, there was some sludgy stuff at the bottom of the bowl too, that could get circulated around I guess. Edited January 25 by GWNORTH 1 Share this post Link to post Share on other sites
