I have been given a modle 4SG 4 hrs 2 cycle engine. I would like to know what the engine compression should be. It tested out at 60 psi. Which seem very low compaired to engine I have tinkered on. Any help on this would be great.
After only 4 hrs 60psi means nothing. Break it in, then worry about compression. No, don't worry about compression unless you have negative symptoms.<br /><br />Hypochondria can include engines, too.
