I performed a cold compression test today as motor has been acting up. Rebuilt carbs new gaskets, floats etc. Readings were 110'105/95 other side 110/105/110. The confusing part When testing all cylinders the engine would stop turning as normal except for the lowest reading cylinder. The engine would continue to turn as long as I held the key turned.
Hence my confusion. This all started with a idle issue and bog down on take off. On plane engine ran out good and was smooth.
Yes, all plugs were out. The other five cylinders after the motor turned over about three times I had to release the key and return again. Just that one cylinder..
