hi everyone, this motor was running perfect my last fishing trip and suddenly seemed to lose a cylinder. cylinder tries to fire at times. the coils have been replaced and seems to have good spark on both cylinders. compression is also good. puuled carb and cleaned all but under the cap...
next question. this block is used to generate up to 140hp. what needs to change in order to go from 100hp to 140hp. sorry, its a 1979 evinrude/johnson 100hp powerhead now.
