HOW did you do the compression test???
You're supposed to prop the throttle wide open.
You're also supposed to remove BOTH trailing spark plugs to do this test correctly.
Did you do that?
If not, the numbers are going to be lower.

yea maybe u should try again i just did mine and it did a 95@114k....although i think the engine was rebuilt without the last owner knowing..(last owner didnt drive it but only a few miles) and i dunno if i have a good battery or not..lol(must be good enough to hit those numbers?)
so yea do it again and check back with us...let us know wats up (at least i know i wanna know what happened)
