1983 Evin 9.9 hp <br /><br />Top cylinder was 96 psi and bottom was 111. I have heard compression should be over 100 and not greater than 10% variance. These results don't look very good, do they???<br /><br />Test was performed properly so I know they are correct. Motor just overheated and I suspect variance is due to that.<br /><br />any thoughts?
