Stupid tuning question part 2

[James Nazarian Jr <James.Nazarian@Colorado.EDU>]

I should probably add that I don't know what size needles are in the carbs
now, but the most choke ever needed to start the car, even on really cold
days, is about 1/3 to 1/2.  When the car is at sea level it runs perfectly
and I think is jetted perfectly, so relative to whatever is in it, how
many sizes leaner would people recomend?
