    1983 Johnson V4 140 Low Compression

    What could cause lost spark on 2 cylinders? Being an old auto mechanic of the shade tree variety, I had an induction timing light and checked each wire, all were firing with one slightly intermittent. Previously I had no spark on 2 cylinders and replaced 2 coils and it did seem to improve...

    1983 Johnson V4 140 Low Compression
