I have attempted to revive my dad's old 1965 18hp Evinurde. Mechanic (supposedly) replaced coil and points and rebuilt carb. Would't idle. Mechanic adjusted points. Idled fine. Second outing with the motor, it ran great for 15-20 minutes at full speed then started missing and shut down to about 25% power. I have decided to go at this myself because I don't really trust our local shop (I think he replaced original plugs with used ones). Pulled plugs and bottom one was oily black in appearance and damp. Replaced with J6C's. Tried again. Same thing. Hard to start, but ran great for a few minutes then went down on power. Compression test shows 90 in both cylinders. (Is that within spec?) Plug wires appear to be OEM. Could be an issue. Any other ideas? Someone had suggested fuel pump diaphram, but I couldn't find a fuel pump kit anywhere. Just replacement pumps. Is the pump rebuildable?
I am on my way to get a flywheel puller to check to see if the coil and points have actually been replaced.
Thanks for any input. I REALLY appreciate it.
