I have been trying to finish up my wife's 69 fastback and I have found a problem. The engine did not seem to be running quite right. Not a new engine. But the one that was in the car. I checked the cylinders and found 3 an 7 were not firing. I checked the plugs and found #7 was in need of replacement. After a new set of plugs and wires I still had nothing on # 3. I did a compression check and had between 145 and 160 psi on all except #3, with only 30 psi. I am going to pull the valve cover to see if the rockers and valves are moving. The car was stored with an open intake manifold for 8 years before I rescued it. Does anyone have any other suggestions?
