A club member has a non revlite 049, that just refuses to run.
With the needle valve ALL the way out the engine will run for a minute or 2, then quit like it overheated. No mater what we cannot richen the thing up at all. The needle is only held in by a few threads, its open that far. Prop is small enough (5x3 rubber duck) so prop load isnt the issue.
The tank seems good and there is not crap in the needle valve. Fuel is the same that I run in my norvels, and it is fine.
The case gets pretty hot, is this a tight bearing situation?
What do we do?
Less compression?
