Penguinpizza 6 #1 Posted April 21 Ok so here is the thing I just bought a Toro Wheel Horse GT410 with a Kohler cv460s motor. It will start up but quickly seems to stall out. I replaced the fuel pump, carb, and battery. After replacing the carb I did notice it started better when it did start but didn't last long. Next I'm thinking the vacuum line. Can anyone offer any trouble shooting into what might be so my wife doesn't kill me thank you 1 Share this post Link to post Share on other sites
ri702bill 11,871 #2 Posted Tuesday at 04:19 PM Welcome! You need to isolate the system that is the problem. Is it fuel or spark related?? A simple inline spark checker ( or 2 when diagnosing a twin cylinder) will help identify if the problem in the spark department. Low cost & good to have... Is the fuel tank cap vent working?? Loosen the cap and try to run it. No cost to try... Is there a fine mesh screen in the shutoff? If there is, they are notorious for severely limiting fuel flow as they get older - particularly if ethanol fuel (a no-no) was used.... Download the manual to see if the OE shutoff had one. Note - IF it was ever replaced - all bets are off & the only way to tell is to replace the shutoff & bushing. Short money... 1 1 Share this post Link to post Share on other sites

Only thing I guess I have to ask is where might the shut off be? By the gas tank is what I'm guessing I'll definitely look into those things 1 Share this post Link to post Share on other sites

ri702bill 11,871 #7 Posted Tuesday at 07:31 PM Shutoff is usually on the bottom of the tank. Usually..... 1 1 Share this post Link to post Share on other sites

Lagersolut 797 #9 Posted Thursday at 02:04 AM Is the unit on Ethanol ? Ethanol degrades rubber fuel lines, the fine rubber particulates end up in the jets - worked on a K181 a few years ago P O also tried a new carb, the degraded fuel line clogged the new carb up in a short order . After another carb - new fuel line and Ethanol free gas running normal again . Just putting it out there 1 1 1 Share this post Link to post Share on other sites

Penguinpizza 6 #12 Posted Friday at 05:23 PM Thank you everyone for helping, I got it up and running yesterday and mowed the grass. Only thing was the choke had to remain half way or it wouldn't act right but hey it is running and cutting 1 Share this post Link to post Share on other sites

Only thing was the choke had to remain halfway or it wouldn't act right but hey it is running and cutting If I was a betting man, I would say it needs another carb cleaning. Its running way lean if you have to keep a half choke maneuver on it. A way lean condition will make it run way hotter than it's supposed to. 2 Share this post Link to post Share on other sites
Penguinpizza 6 #14 Posted 3 hours ago Used it yesterday and it smoked for like 10 minutes then ran like a dream was able to put the choke where it needed to be and everything. Thanks once again everyone for your help I appreciate it Share this post Link to post Share on other sites

Thanks once again everyone for your help I appreciate it The choke needed to be fully open, was it? I don't play with dirty carburetors and simply clean them instead of waiting for crud to move around and repeatedly cause problems. Share this post Link to post Share on other sites
