Search or look in the FAQ....takes like 2 seconds...anything over 100psi is a healthy engine. Look here for more info: http://robrobinette.com/compression.htm

3 even bounces of 100 PSI or above is GOOD. Readings of 125PSI is GREAT!
3 even bounces of less than 100 PSI indicates that motor is getting tired, and 85PSi or below indicates the engine needs a rebuild very shortly
