[Tigers] Air Fuel Ratios

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
