140 hp Johnson

[shurlock]

tried the compression tests turning it by hand, I also tried the compression test using the starter motor from the engine. I tried the compression test with the motor advanced and also with the throttle open.I even tried removing the Schrader valve thinking there was a restriction. all the same. I purchased the service manual for the Johnson. will read it and pull one of the heads tomorrow and let you know what I see. "spareparts" I am looking forward to hearing from you. "Spareparts" seemed very knowledgeable about the engine wish I followed compression test first.
