Thanks. I’ll keep this in mind.

The only other thing I can add is what I ended up doing on my stubborn 69 6hp.  It kind of ran like yours, a little fussy starting, strange idle needle adjustment, and bog/lack of WOT power.  I wasted alot of time looking for problems that were not there.  Finally, upped the high speed fixed jet from .044 to .048″ which solved all the issues.  Don’t know why this was necessary, perhaps just an old/worn carburetor.  There were about three different generations of carburetors used on these engines, so I’m thinking your high speed jet is much bigger.  Have you removed it from the carb?  Soak it in strong carburetor cleaner.

And, I would agree with you, this is not an ignition/timing issue.  The timing light shows that it is set to the advanced side, which is fine and wouldn’t cause the issues you report.  OK, won’t pound this thread into the ground, seems like the engine is running OK now.
