carb tuning help

Timing FIRST!

If it doesn't have at least 20* initial you aren't in the ballpark is my guess.

I'll guess the cam has 245ish at .050 for duration?

Get the initial squared away, then start in on the carb idle settings

i have the engine timed at 36* total timing all in by 2500 rpm. my msd dizzy has 21 degree of mech. advance built in. i have the medium springs in the dizzy.

based on that it looks like i would have 15* initial. i can change the bushing and bring it down to a total of 18* mech. advance in the dizzy and set the total at 36* and initial at 18*.
