I have a troy bilt snow blower with a tecumseh engine and it starts great and runs great. Most of the time, anyway. It will scoop up snow and throw it just fine, and then for no obvious reason it stalls. If I leave it idling with no load it runs fine endlessly.
If I put load on it (engage the augur or the wheel drive) then stop, after 5-10 seconds after I stop it will stall. I've replaced the spark plug, I've taken apart the carb, cleaned it, cleaned out the jets. I don't know what else it could be.
When it's about to stall, if I pump the primer it will catch and start running fine again until I put some load on it and relieve the load again. Sometimes the same trick works by closing the choke, but I have to be quick and often miss it and it stalls.
If anybody has any suggestions of things to try to fix it, I'd appreciate it.
Not sure if this is exactly the right forum, but it says 'mechanics' not 'cars' specifically.
