man that's a lot of initial timing.. but if it isn't pinging.. what is the compression ratio? I cannot get that much and I am about 10:1 or just over that.. maybe 10.3.. and I get it kicking back at 15-16.. and then it pings at mid throttle under load.

A good "dial indicator" is a 1/4 inch wooden dowl carefully inserted into the chamber and cranked by hand to determine TDC. I said five degrees as an example. Within a few degrees plus or minus might have been a better example.. Zero is ideal, but it almost never happens that way.

Regards,
