Opinion on this Spark plug reading.
I have been reading up on how to tune by reading the plugs lately, Its seems as though this is a learning process that takes some time and understanding to be able to be accurate. I have read quite a few posts by YR as well as RRR and the other experienced posters on this form... These plugs are Autolite #65 in a 71 340. Hydraulic Roller shaft. Air-Gap with QFT 650 DP carburetor with stock jets and squirters. MP distributor curved to 34 total 15* initial and all in by 3000rpm. No vacuum advance. Any opinions on this would be appreciated.
