Well...... the story continues. The atomic 4 now runs. After testing again: The fuel pump, coil, distributor, spark plugs,, spark plug wires, condenser, points, and compression. All where found to work.
Compression on cylinder one is 90, cylinder 2 is 90, 3 and 4 are 110. Unfortunately it only runs when spark plug #1 is out of the block. This results in massive fume buildup in the boat, but it actually runs.
Now, some more help please. I am a bit stumped.
Why would it do this? I have 4 sparkplugs in and it will not run. I take one out at it does.
Some dockside experts say this could be anything from a blown head gasket, to a stuck valve, a warped or cracked head, or gunk on the rings?
I put marvel mystery oil in the spark plug holes while I meditate on this once again.
