Re: Martin 20 won’t run

[jerry-ahrens]

I’ve ran into a lot of Wico condensors that were weak. Does that engine have O-rings on the valve skirts? I have a Martin 45 that had those O-rings, that were hard and dried out. They would leak crankcase pressure very badly when cranking the motor. I got replacements from Russ Larson, and that fixed the problem. That motor wouldn’t even make a ”pop” when trying to start it. Just an idea for you to consider…
