1/1600 carb questions

[westtexasbaja]

What's the difference between a 30 PICT 1, 2 & 3 carb?
Which is best for a 1/1600?

What's the difference between those and an H30/31 PICT?
I have a H30/31 PICT and was told it was not legal for this class. True?

Thanks,
G.

Score Tech said the H30/31 pict was legal.....

Found this to........

30 PICT-1
1966 and 1967
This model is similar to the 28 PICT-1 except that it has a larger venturi. This model also does not have a power fuel system.

30 PICT-2
1968 and 1969
This model is like the 30 PICT-1 except that it does have a power fuel system.

30 PICT-3
1970
This model is similar to the 30 PICT-2 except that redesigned idling permits the throttle to completely close at idel, while idle speed is controlled by air bypass around the throttle.
