Engine not used for 5 yrs. Before startup replaced all electrical parts...distributor, plugs, ignition wires to plugs, emptied gas tank and flushed fuel lines, rebuilt carb, new batteries, new fuel pump diaphram, compression test...1cylinder 95 rest above 105 to 120 also new water impeller.
Problem 1
Gas leaking into oil which is leaking pre- shaft through gasket into bilge.
2 cylinders not firing but fire with exchange of wires from cylinders that are firing.
The exhaust has abundance of gas discharge.
Next approach;
All new plugs and wires to plugs. Oil change and watch for aft engine prop junction leAK
Hoping oil viscosity will seal the leak and having all cylinders firing will eliminate the exhaust of gas.
Anyone with suggestions?
