My 2 stroke 40 hp has lost one
My 2 stroke 40 hp has lost one cylinder (the bottom one). Compression is 105 on both cylinders. Removed both plugs and hooked up the plug wires and spun the engine and they both were firing. Took bottom plug and put it on top cylinder and it worked there. The top one didn't word on the bottom so that ruled out he plug. What I don't understand is why the bottom one isn't firing although I see a spark. Could it be that the spark is to weak? Can someone please give me some advice? Thanks...........
