Hello folks. Mower is a Craftsman 917.2566111 with a Kohler command 15.5 CV15S engine.

Put fresh gas in this morning and got my front portion cut and all was fine. But suddenly my mower starts to die down. I thought it was bogging because i hit a thick patch, moved the choke up and it came back to speed, but dies when i move thottle to mowing speed. Engaging the blade causes it to die.

Oil and filter was changed 2 weeks ago. New fuel filter was added as well.


Thanks for any help.

Likely some crap or water in the carb.

I cleaned the carb as best i could with cleaner, and put some B12 in the tank. Also this place had gunk in it, don't know if that would cause problems with the speed.But its running back normally now. Tried my best to kill it but it kept running. Hopefully it stays that way.
