new problem, on my 1961 18 hp johnson. for some reason, it will spark for a few pulls, and then it quits sparking. i took the flywheel of and looked around and everything looked fine, put the flywheel back and and got some spark for a few more pulls, and then lost it again. it seems like if i take the flywheel off and put it back on it gives me spark, but it keeps losing it. oh yeh, i just replaced the coils, points, and condensers. it was working fine yesterday. but the spark just keeps going in and out. have any ideas?
