Anyone know how long the vented screw that goes up from the thottle body to the carb is supposed to be?
I'm rebuilding a non-USA 1977 carb (H3660 tag) and am missing the vented screw which I think is PN 21824-38010 Screw, Set, No.2(For Carburetor Body Set) and from what I can tell, is a standard part for a bunch of models and was the same on US and general market carbs. I managed to track down a used one, but it is too short and ends right at top of the insulator block. I'm trying to figure out if the screw I bought is broken off, or if I need a different part number for a longer screw.
My non-EGR insulator is 20mm thick and the screw I have is 43mm long and has 13 threads on it. Anyone have any idea either how long this screw should be on a 1975-80 carb, or how thick the insulator block is on a USA spec carb (to see if my problem is that the non-EGR insulator is thicker)? This screw is still available in Japan, but before I pay for shipping, I'd like to make sure it's the right screw. I know I don't have the pre-1975 shorter screw as I previously bought one of those, which is way too short.
