I retarded my timing to 32 max and it runs better than ever.
50 f8 idle
F9 emulsion tubes
4.5 aux venturis
Even before I changed the ignition timing I noticed a very quick lean out begining at 6200. Right below that the afr showed mid 12's. Within the space of 100 or so rpms it jumped to the mid to high 13's. Kind of scary actually.
From what I've tried to soak in changing to a f11 emulsion tube should help. There is no "B" hole at the bottom so no braking action at high rpms = richer, Correct? Any comments, suggestions would be appreciated. I don't usually run up there but seeing that lean out got my attention. Head is ported similar to my "headwork" thread. HD valve springs, big intake valves, opened seats, exhaust valves are stock. Shankle headers.
The passenger seat is 15 miles an hour faster than the drivers seat.
