It was a snap. Took off engine shroud.
Unbolted carb. Two bolts.
Disconnected throttle linkage.
Gave it a good cleaning
Reassembled in reverse order with a new gasket.
All parts fit perfectly and it started right up.
Note-Now I use only ethanol free gas in my gas powered lawn equipment. I have had problems with ethanol gas even using Stabil.
