Pinging

D'oh re me. What do I do? This is just the standars Blue cap HEI distributor that came out after they got away from points. So how much mechanical advance do these units offer? Just curious. How much total do you run? If you start with 20 then you must be over 40 right? I am trusting this timing light of course. But when I set it to Zero at idle the mark is right on 12 BTDC. When I set it at 12 , the mark is spot on at TDC. What I will do is see if I can measure the diameter of the damper and creat a degree scale for more accurate readings. In the mean time I will leave it where it is and as soon as I get the brakes fixed and get it registered and insured I will be able to street test it.

What about the carb? Holly 670 is what the receipt shows, but it is not chrome like the one that holly shows.

Oh and it has been a long time since I tried to read plugs so if you would like to school me on that I would be much abliged. I seem to recall you do not want to see to white, especially with little grey deposits which would indicate PING. Like the best is a light grey. Black being too rich. Am I correct on this?
