89 PG3 What should compression be
I have a 1989 EZGO. that will not start!
I believe it is a PG3 engine? Compression tested to 120 psi. Ran leak down test and was seeing gas coming out of the crank seal. Reed valves look good. I have already went through the carb. Am I on the right track????? Is a 120 psi compression enough for these type motors? Can anyone help a new guy out??? Thanks, Pete |

Compression is low. Should be 140 or more.

Re: 89 PG3 What should compression be
Doesn't really matter - 120 is low (not terrible - but low). Do you have a "warm" reading?
