Thanks for the pdf write up Bud; its very thorough informative and extensive,
and
yes will save many going through all those experiences to find a solution...
On the issue of this thread, have you used a dual meter to observe left/right
manifold
pressure readings through operating rpm range and while the vibration
at 3500rpm is active, flickering needle on either gauge will indicate sticking
valve; theres also small chance one of the choke valves is not fully returning
to correct position, or a carburettor piston may be binding intermittently on
the slide... then again it may not be fuel/carbi related.. if you have access
to two verified good carbis then swap them out and see if the issue
disappears...
will be interesting to see what it ends up being !!
