Hi All
I have old johnson 20 HP 1973. There is an issue with the spark on bottom cylinder. The spark is weak and intermittent. But on upper cylinder the spark is very strong. I changed the both set of ignition coils, condensers and point breakers. I left the old driver coil. I adjusted both point breakers according "Set"
on the magneto cam. Does anybody idea why the bottom cylinder spark is so bad?
