I have had this engine for some time, New front bearing. Engine has less than 1 gallon on the pistion/sleeve. running Odonnell Fuel/Odonnell Glow plug no 99.

I have taken the engine appart, inspected it and all appears fine. Engine was resealed with engine sealant. Carb sealed also. Stills idles high.

At first, I thought there was bubbles in the fuel line a I cleared the bubbles and still idles. Fuel tank was removed and pressure tested for leaks. Non I could find.

Using clear fuel line so, i didn't see any cracks.

Any suggestions??
