Street Demon tuning experience

I found out the engine doesn't like 35 degrees advance, at least not all the time. When hitting the gas in 4th gear around 35 miles per hour I got spark knock that I have never had before. At least I know what that sounds like now. The starter also kicked back when I tried to start it hot, so I backed it down to 30 degrees. As far as I could tell, both symptoms went away, but I'll have to drive it some more this week/end to see if the starter kick back is really gone or not. I left the distributor advance locked out because I'm too lazy to take it off and try to set it again. If I have to back the timing down again I'll reset the mechanical advance.

The other thing I did was put in the 62/54 rod. When I had the 64/56 rod in there was a little bit of hesitation that I figured I would take out with a nozzle, but I went down one rod size instead. The carb runs great in this configuration even though it shows really rich (Cruise is around 13, but acceleration is 11-12 and WOT gets richer). I'll run it like this for a while and see what kind of mileage I get.
