As I read your post, my feeling was leaning towards the same conclusion as Fleetwin….possibly running on one cylinder at ilde and below transitional speed. If it were me, I’d run the engine where the problem is the worst. Then, stop it dead immediately and remove the plugs for inspection. Is one drier than the other? is one more wet than the other? At idle speed they should both be the same and kind of moist. Not dry and not soaked, either.
One the other hand, the relationship to where the mag is, as opposed to how open the throttle is, is critical and usually adjustable.If no one else knows, I think I can look up how to check this very important "synch and link."
It would help in trouble shooting to do a compression and open gap, cranking spark test, as a baseline. Spark should jump at least 1/4".
I’m not familiar with this exact motor but West Bend engines usually run very well; so I am sure it can be worked out.
Long live American manufacturing!
