Misfire at cruise, popping/afterfire at 3000RPM
Getting back to troubleshooting the 440. I began where @67Dart273 suggested and made sure my grounds were good, but before I started it to check voltage, I popped a valve cover off so I could visualize the rockers.
From working on the 318 in the Scamp, I remember being able to EASILY recognize where each cylinder was in its stroke by looking at the angle of the rocker. However, this engine looks different. I can’t tell by looking at the rockers — they all look to be at the same angle! I thought my eyes were playing tricks on me, so I laid a straight edge over them. The engine is at #1 compression TDC. See for yourselves…..
