Re: Cylinder compression specs

Seems there is at least a consensus on how to calculate - use pressure at altitude expressed in pounds per square inch multiplied by the compression rating. Because I’m at just a skosh above sea level and the compression ratio per spec for the 359 used in the 5431’s is 8.7:1, I should expect to see ABOUT 127 psi if all the planets are in alignment! LOL

I think we’ll move forward by putting a bit of oil in the cylinders (maybe one to start) to see if there is any difference. Then, go from there.

Thanks again!
