Boatright,<br /><br />Are you sure you don't just have a couple of stuck rings?<br /><br />You can decarb. it and the compression might come back. Maybe you'll want to keep it or, at least you'll get alot more for it.

Boatright,<br /><br />Are the two "low" cylinders on the same side?<br /><br />If so, a head gasket could be the culprit.<br /><br />Don't want to run you in circles here-just trying to save or make you a few bucks.

djohns19 ,I started motor after setting for a year and did a compression test it was 110 70 100 100.Head gaskets seem to be fine.

boatright,<br /><br />The only one that is out of sorts is the 70 psi. That still could POSSIBLY be a head gasket.<br /><br />It won't hurt to pull the head off and have a look. You'll know then if you have deeper trouble.
