My dad brought home a cylinder compression guage from work today to test the psi. in his Corvair. I decieded to pull out the Chiltons and check the EB. Chiltons, said that I need 150 psi. When I tested each individual cylinder I was getting 80 to 100 psi. I am hopping that the discrepancy is in the guage. It isn't a screw in type, but rather a rubber end that you press up into the spark plug holes. I pulled all the spark plugs out and pressed the guage up into the hole with as much force as I could and some air would escape out the sides anyways. Am I using the right guage or is my psi. that low. As a side note, the guage worked just fine on the corvair and the psi's were right on the money.
