courage 22hp starts hard when hot

Hi there


I have a 2007 Toro 50" Courage 22HP lawn tractor with a kohler engine. I'm having trouble starting the engine when hot. It has done this for a long time. When it starts cold, no problem, but after I shut it off and try to restart, the engine turns over slow and sometimes won't start until I let it cool off. The starter was replaced when I got it as it did the same thing I guess.

I wanted to check the valves but I read they were hydraulic.....Is that true?

What else could I check, adjust or replace to make the engine turn over normally when hot?


thanks

Yes the valves and hydraulic lifters. I take it it cranks over slowly when hot then? Its normally easier to crank when hot so that's strange?

try adjusting the valves....the compression release won't work if out just a little and when warm might be out more due to expansion?

I adjusted the valves as they are not hydraulic, only the heavy duty newer engines have that I was told.



The valves weren't badly out of spec but I adjusted them to .005" (calls for 4-6 thous for each)


The starter drive gear tends to stick up into the flywheek and doesn't always return back to the bottom..



I found I can buy a drive kit but I may need a new starter as mine is now 12 years old. I've got it at Toro right now having the tranny fluid changed. I usually do everything on my own but found out there is something tricky with that. We'll see what Tor says when I get it back.
