[Tigers] Air Fuel Ratios

[Sandy Ganz]

I don't remember where I saw it but somewere it has some info on how 14.7 was
chemically the best number but not for the best power (in the 12's rings a
bell, but hit the web for more data). Might have been on one of the tuner
sights or something where they have the cars on the dyno and doing fine fuel
map tuning. I would guess all cars from the era ran on the rich side of things
especially from the hydrocarbon producing 2V autolites ;)  

Like Bill Cosby

Hi
all,

Well I hadn't driven my tiger in a while and it seems like something in
the 
carb is gummed up, and the car seems to be running very rich.  I plan on
trying to get some carb cleaner though it to clean it up and make it run
better, but I thought I would also ask a question that has interested me for
a while.

What air fuel ratios should a 60's era V-8 running a carb?  I know
that 
'ideal' ratio is 14.7, but If I remember right, ideal ratio is too lean
for 
a carb since it doesn't have the fancy O2 sensor that a factory Fuel
Injection system would have.

I also assume that there are probably multiple
air fuel ratios that you 
should shoot for, depending on whether you are
idling, heavy load, WOT, 
light load cruising, etc.

So anyone have any nice
simple rules of thumb for street cars?

Thanks,
Steve
