Some friends of mine own several airplanes. One is a 1932 Aeronca "k" model with a 2 cylinder engine. It is in my hangar and I have been helping them in attempting to get the engine to run again. It was rebuilt but we have had problems with both carburetor and magneto.
Finally got it to fire for a few revolutions the other day, first on both cylinders and then it switched to one only for a few seconds. It is pretty amusing. Has straight pipe exhaust and sounds like a Harley.
Magneto is a 4 cylinder unit modified to work with two by using a distributor bar that goes all the way across and "connects" to two HV contacts at the same time. (We didn't design that, chuckle, but it is pretty clever).
My take on the problem is that one HV ignition lead is intermittent arcing/shorting out.
More later as we find the problem(s).
