Who is BS'ing who?

stock jetting is basd on sea level, so if you're higher than sea level...jet down, google a jet program...or it's 1 jet per 2000ft so holley says...but it could actually be 1 per 1000ft.

you could run more initial timing imo
U should raise the initial up, it bring low speed snappyness and better milage, see if you can raise it to 24* while warm and start it, if so....cool, limit the mech advance to say 8*...so 24*+8*=32* + vac adv=52*

around 30-34* total w/o vac advance is good with a closed chamber...but raise it higher if it likes it..
the vac adv sounds good where it's at.
