Good compression?
I took a cold compression test on my rebuilt engine (stock bottom end) and came out with 125-140 psi on average. (with all of the plugs out)
These new piston rings only have about 75 miles on them, but they went through alot of abuse from unburned fuel & idling with oversized injectors.
So is this good pressure for a cold check on a new engine? I can't fire it up yet to check it warm.
