VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1929-1932 W - ! carbs

have two carter W-1 carbs, one with number 20 cast in carb above Carter w-1 name and the numbers below 1851615 and 2134534,
the second has number 23 cast above carter w-1 name, the numbers below, cannot read

can any one advise what year they would work on, the guy who sold said would work on our 1930, it is a rjh - 08

thanks Dave

The 1930 does not use a Carter W-1 as they were downdraft carburetors. The Carter RJH-08 is an updraft. The numbers cast in were pattern or mold numbers or patent numbers so don't help with identification of the application. The number of screws holding the float bowl cover, air horn are clues. As are straight or dog-leg throttle arms, single plate or two plate chokes, round or flat accelerator plungers are much better to identify. Of course after ~ 80 years modifications are likely so the original application may not be how the carburetor is currently set up.

Chipper, Thank You
Think first down draft was in 33??
Trying to figure out to help identify to provide / sell them to some one in need of W-!..
Will look based on your descriptions above.,
thanks Dave

The first downdraft was in 1932.

Chevrolet Carter W-1 carbs

Jon.

The first downdraft for Chevrolet was 1932 Carter W-1 with the idle adjustment screw just under the air horn. The 1933 looked the same but had a port for vacuum in line with the throttle shaft. Jon Hargrove "Carbking" has put together a dynamite website with beaucoup information on all kinds of carburetors. http://www.thecarburetorshop.com/CarterChevroletW1.htm Should get you to the pages to identify your W-1 carburetors.

thanks everybody
