Trying to save a little $ on gas, I leaned out the carb a bit.  The stong smell of raw fuel, by my freinds behind me, led me to belive I was running a bit rich. So  180air corrector(p&s)140 main jet(p) 150 (s) and a 16(holley 5200 p/n)(p) F-6(s) e-tubes and 50(p) 55(s) idle jets on weber 32/36 from 160 air(p & s) 150 main (p & s) 060 idles. Leaned the air(bigger) and main jets(smaller) and put a richer e-tube (holes smaller, lower) in the primary fixed the choke linkage, it was partially on, and pulling out of my parking spot the tirres chirped on accedent!
