Hey everyone
I have a 03 exmark laser-z with a kohler ch25s engine. Recently had a bent pushrod, I replaced all the rods and lifters and lapped the valves, the whole 9. All this because the mower would bog down when trying to go full speed. If I let up on the throttle it would rev back up. It will idle perfectly fine full throttle, but the minute I try to go full speed it bogs down. The right cylinder is running great. The left, not so much. When I let the engine just run on the left it slowly stalls out. So, fixing the pushrod issue didn't solve my other problem.
Any ideas on what the issue may be?
The left cylinder definitely has spark, it gave me quite a shock when pulling it off to test it.
Thanks for your help
