OK; the first two videos were with the original carburetor. The one that came with the engine in 1964; modified only by putting the older bowl assembly on.
The video linked below is the engine with a different carburetor; from another 1964 Lightwin. It has the fixed HS jet #28.
I think it runs better; there is less variation in RPM. But; it is still not perfect. I guess this is the best this little motor can run. It actually runs fairly well; just not like it really should. But; it’s had a hard life. I imagine it has a bunch of hours on it; the cylinders pistons and rings looked ok; but I have no doubt that it all has a lot of wear.
I have only a basic understanding of "primary compression". I have been assuming that with the compression I measure with my gauge…the engine should run well.
As for the idle; it idles pretty well; I think. There again; maybe not perfect…
fleetwin; you’ve asked a few time now about the reed assembly. Sorry for ignoring that inquiry. Yes; it has been disturbed; early on I swapped the two pieces from another parts motor. I replaced the gasket at the crankcase; the two halves were not disturbed. The swap yielded absolutely no change…so I doubt there is an issue there.
