Hello all,
I have a 1986 Force 50, the issues is it’s running on 1 cylinder (the bottom cylinder), I’ve replaced the spark plugs, checked compression (137 PSI in the top cylinder and 130 PSI in the bottom cylinder), checked the ignition coils by switching the bottom coil with the top coil and they are both working. I still have no spark in the top cylinder. Any advise on what to look at? I’ve attached a photo and video to display what I’m dealing with.
- Thanks
