I have a 1954 Johnson 5.5 hp. Its been sitting for a long time and was locked up. I shot penetrating oil in it and worked the flywheel back and forth by hand until it spun over freely. I to ssed a compression gauge on it and both cylinders gave up 90 psi compression. Is this to low or should I try to start it?
