Anything lower than 93 will ping constantly no matter what the timing is set at. And then when the Rpms start getting high, like around 4900 and higher, it pings no matter what. I need to mix in a gallon or two of 104 ocatane probably.

I'm not sure what my timing is actually at now. I have to figure out this weekend where Top dead center is on the dampner and make a mark, the lack of advancing and retarding timing is killing my power. My guess is I have it at somewhere around 9-12 degreess about now, when ever I hook the advance up, it pings like crazy. I didnt have time to mess with it so I just unhooked the vacuum line going to the advance.
