1971 Evinrude 4hp (help again) :-)

[dazwitten]

Help again lol, i have been trying to get this engine running for a while, got it for next to nothing, i am trouble getting it started, thought it was a fuel problem but since have done a compression test and have no realised that the bottom pot only has 55psi and the top one has only 5hp :-( no i am aware that this is gonna cost a few ??? to repair but people seem to love these engines and i think it will be a good investment.

so where do i start could this be head gasket ???? or rings etc????

Cheers Guys

Take the head off and have a look inside. Rotate the crankshaft and run your finger inside the cylinder walls. Look for signs of broken rings like scratchs on the cylider walls. Chances are that you have a blown head gasket and that's not expensive to replace.
