kgbg, buy a compression tester. It's hard to predict with different compression motors, that's why you should just get one and test yourself. Comp. testers are excellent way to determine if you need rebuild, assuming you test comp. immediately after rebuild.

Hope this helps. BTW I have my #'s at home and can get ya later if ya need them.

thanks Chad,
I have one, have been taking readings for quite some time. I am looking for some comparisons, its just the info nut in me. I like to have numbers, logs, books, reference ect. Let me know what you #'s are if its not too much to ask.
