Can't get it to idle or run full thottle. Rebuilt carbs, has good compression and new plugs. Ran fine after carb rebuild at full thottle for 10 minutes but never idled right. If I keep hitting the electric choke it will idle.

When I try to run full thottle it acts like it's running at half thottle with a muffled thumping sound coming from the engine.

Whats a feller to do?

Check to see if there's a plastic part that has "melted" due to ethanol in the starter solenoid. I remember guys bitching about the same problems Johnson's around that time period.

This is it.  Make sure those jets are clean.  I had trash in mine and the same symptoms occurred.

My next thought would be air leak.
