There is a first time for everything updated three fouled plugs

I forgot the other value on the gauge. It started with a K. 23-25 lbs was the other value ,but I did think that was the one used for automotive compression. I thought the numbers were always higher like 100-120 when talking about a motor. The main thing is that they are all close right?

I have a new spring coming Monday. Should be on Tuesday or Wednesday. Do you think I still have a problem? Thanks again for your help Chris.

Chris I checked out your site that is a pretty sweet olds motor. My first car was a 81 grand prix that I put a olds 403 into. The motor did not rev high ,but it did put you in the seat, even with the 2.29 single track once it hooked. God I miss the good old days. Timing and carb what else was there.
