Here are my notes from my racing logbook this year:
Carb configuration: 40 IDF Webers (Italian) Venturis 28mm Idle Jets 60 Main Jets 115 Air correctors 200 Emulsion tubes F11 Accel Bypass valve .55 Float valve set to 14mm (closed) to 24mm (open) I since changed the mains to 120, but I dont feel much of a difference, but my AFRs dropped a little lower than necessary. When I collect all the AFR data from a race and average the WOT data only, I get ~12.5-13.5 AFR. EGTs never get above 1200-1300 This is with a webcam 86b. stock heads, 2056, 5000 ft. alt., 91 pump gas. Mallory unilite, MSD 6AL 34 degrees advance at 3500. I am considering going to larger venturis, but I run almost exclusively at high altitude, and havent sprung for the $$ new 32s. I would LOVE to have a peek at Eric's spreadsheet! :-) |
