| 390 pinging? |
| By Doug Bender - 05/30/2004 10:55:28 PM; IP 66.216.130.115 |
I'm having some pinging with my Fairlane's 390. I'll start off by saying that the ignition is one area that I've never dealt much with and really don't know much more than setting the initial timing. I currently have a stock vacuum advance distributor with a Pertronix Ignitor installed. I have the initial timing set for 10B as the manual says. I think I have everything else correctly set (the simple stuff) but I'm wondering about my vacuum advance and if it is working correctly? I have a Mity-Vac vacuum pump and I'm not sure exactly how to use it to check my advance. I did hook it up with the engine off and apply vacuum to the advance to see what it does. It appeared to stop moving with 7.5 inches showing on the gauge. Anyhow, I'm no expert and was wondering if anyone has any tips on how to get the ping out. The compression is about 10:1 and I'm using Sunoco Ultra 94. I'd like to get this worked out so I have a pleasant cruise to Fords at Carlisle next weekend.
Thanks,
Doug |
