1969 Evinrude compression?

[Howard Allen]

Hi;<br />My new to me engine tests cold at 110PSI, both cylinders. After reading some of the other posts on the list here I am wondering if that is too low?<br /><br />I started the motor successfully on the 4th pull with last year's gas (previous PO) and it seemed to run fine for the 30 seconds I ran it.

Howdy Howard. Your compression is fine. The general rule is: Over 100lb and within 15lb of one another.<br /><br />Big risk using last year gas. . . very likely full of varnish which is deadly to carbs, reeds and rings. If it has Sta-Bil in it you probably dodged a bullet.<br /><br />Smooth sailing.<br />JB
