Question about Craftsman 20 Hp 42" Deck Lawn Tractor
After mower has run for sometime, it tries to stall. if I pull the choke cable out i can get it to run fully again. Also it does not want to start after it has run for awhile. Any ideas
I had the same exact problem with mine :) I adjusted the valves and cleaned the fuel bowl on the bottom of the carberator, and it helped for a while, but started again a monh later. Recently, I took the head off and found a large amount of carbon deposit in the head and on the piston. I believe the new 10% ethanol fuels don't burn as cleanly as before. You may try to run a higher octane fuel or a small amount of fuel system cleaner through the engine to try to remove these deposits. Let me know if this helps :)
