Quote: Timing is set at 5degrees ATDC...No ping/detonation with 91 octane fuel...Trial and error on the base timing. Whatever the actual value is, I have found what this combo of parts likes.
I think you have a slipping timing mark on the vibration dampener. Get a piston stop tool and find out exactly where TDC currently is in relation to your timing mark.

Read-up on distributor recurving... because... More over-all performance is in there, waiting to be "unleashed" with some carefull distributor work. Basically, if you decrease the amount of total mechanical advance by 10 degrees, you can re-adjust the initial timing to 5 degrees BTDC (+ 10 degrees) to get a little better off-idle and low rpm performance... with-out higher RPM pinging. And yes... confirm that the timing mark is correct, before starting any distributor recurving work. DD |

Thanks guys. A distributor recurve is in the plans. I am going to get a piston stop tool and find TDC first and proceed from there! |
