with a spear spark plug replaceing the decompresor and trning over slowly by hand, in one rotation thete is two spots witch have resistance to rotation the first being harder than the second, when pushing through the first spot i can hear a small noise of air squeezing through really small gap and sounds like its from inside the engine.
the other spot is not as strong and ends with a small pop.
does this sound normal?
thanks for your time and help
