Original carb specs 7045214

(1/2) > >>

scrappy:
Anyone have original primary jet/rod & hanger/rod specs for a 1975 chevy truck carb 7045214?   I've had this carb since 1980, and might have robbed the original parts out of it.  Has a 77 primary jet, I think will be too rich for the mild 350 we are building.

Thanks in advance.

Thanks mudsport.  Looks like it will be too rich.  Plan is when we get it running is to see what the wide band shows and go from there.

 Just to clarify, it used 39B Primary Metering Rods. Not 39 Primary Metering Rods. And it also used the "K" Secondary Hanger as well from the factory. 8)

"b" rods are used  only with APT in the throttle body correct?  And these are different than the rods used in the 170 series carb that had the APT under the air horn.
