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 total number and then start in on the carb idle settings. If you give the distributor a little bit of a clockwise twist and your idle RPM increases, it wants the timing.
