Once I get past the funky start up idle, she runs good. No flat spots, no hesitation, but I'm just questioning whether there can be an improvement.... As I have been less reluctant to stomp on her once and a while,i do notice some faint pinging sometimes and none at other times...
Removing the CHT sensor spacer I had made, I think she's a it rich at idle for too long....
ok, the rich at idle not so much a concern, the pinging I would worry about and avoid those conditions. If you can hear the pinging over the engine /road/wind noise, you know it has to be loud and harmful.
you got an electronic ignitoin and that already is a big improvement over stock.
i got a 2056 JE piston motor, Elgin FI hopped up cam, Bursch Ex. and run the stock D jet and Stock D-jet Dizzie with stockish settings, maybe a slight degree or two dump up in the timing setting, not much. enrichening the mixture via the MPS made the most perfromance gain for me on this motor. You might want to play with your mixture a bit more, and try the stock dizzie, but maybe see if you can get away with a little more advance than specififed as your motor and more importantly your cam are no longer stock.
I assume you have more valve overlap on your cam, and thus can afford to push the advance a little more maybe. (Since your dynamic compression ratio will be lower) you will want to do this on high test gasoline, not regular low grade.
