I have a Johnson 15 HP 1974 that is sparking well on the top cylinder but the bottom cylinder has a weak spark. It has a PSI of 120 on both cylinders. Any ideas on what to check to verify what is causing the weak spark on cylinder 2? The motor will backfire every now and them but will not attempt to start at all. Ive taken the flywheel off, the points look good and I lightly sanded them to make sure there was no corrosion. Any ideas or troubleshooting tips appreciated.
