After a couple of test runs, I had to retard the timing to stop the detonation. First retard about 3deg. then had detonation at WOT then retard some more until gone. Parked and check timing. Shows 8deg BTDC with vacuum, off of the tabs at ATDC abiut 2:00 with advance disconnected. I'm beginning to think the marks arnt right or something. Any way, I dont have detonation now and need to drive it to work I just been confused during this whole deal. Dont know which way is right or which way is wrong.
