Nikki jet sizes are they based on wire size or what?
so for example say my primary is a 70..
would a 140 be twice the size or is it indirectly porptional?
make sense?
anyone know?

you are the man
im converting to the car to run on alcohol.
so i have to ~double the jet size since it takes about twice the alcohol to run stoich as it would gas

) had him look at a spare carb i got laying aroundhe said with the holley balck(alky compliant) and some work on needle/float that hes going to do, i shouldnt have a problem with fuel starvation, only reason i am even thinking of runnin alky on the nikki is becuase i dont want to try and run a 48ida on the stockport motor. If i pop the motor oh well im building another 12A bridgeport(slowly).
Im just trying to see how fast i can go on a stockport motor and decided WTF why not go alky.
4.77's go in on Tues and lightweight flywheel and clutch from horsepowerinabox as soon as i get it.

If you double the diameter of the jet, you'll be flowing much more than twice the fuel. The amount of flow is dependent on cross-sectional area of the jet.
pi * radius ^2
3.14 * .35 mm ^ 2 = .3848 mm^2
3.14 * .70 mm ^ 2 = 1.5394 mm^2
Which means you'll flow 4 times as much fuel!!!
In order to flow roughly twice as much you'll need to multiply .70 mm jet by the square root of 2 (1.4142)
.70 mm * 1.4142 = .989 mm
So, you'll probably be a lot closer with a 100 jet.
