Hi my carb mount bolts are almost certainly wrong and bad. What is the correct size?
3 8 x 24
Thanks, what length and is it a castle nut?
Bolt goes head side on carb flange, is 1 3/8" long, hex nut only. Pull it tight to prevent leaks.
I've seen both kinds of bolts used, 3/8-24 and 3/8-16. Length is 11/8". Regular hex nut, not castle.
If you take a 7/16" nut, drill it out and re-tap the hole for the 3/8-24 thread, you can easily put a 1/2" wrench on the nut to tighten it.
Uh-oh. Another controversy. I wonder if anybody has listed all the fasteners on the Rip car. That would be a good reference for what's correct.
Keith, how can you tap out 7/16 hole to 3/8 which is smaller?????????
I think Keith must mean to say 5/16". But I have no trouble reaching the 3/8" nut with a 9/16" socket of the right length. If you need a backup on the bolt, a crowfoot works.
To reduce controversy, check of Parts Book, July 1, '24.
Lists the Carb Flange Bolt as #4130 and in parentheses another part that can be used, #3072.
#3072 is C.C. and Cyl. Cover Cap Screw, and that bolt is listed as being 3/8" x 1" long!
For kickers, the #4130B is the Carb Flange Bolt Nut,
and that has order substitute being #3066B-----"Inlet and Exhaust Clamp Stud Nut"!
And the pitch on those is 24. Controversy settled.
I'm sorry but no way. No cotter keys? ;-) ;-)
No, wait. I have my bolts in backwards. Sorry.
Golly Ignacio, I do hope your tongue was firmly implanted in your cheek but I hear you loud and clear!
My hearing is crap.
20 years ago I used a lotta nylock nuts on my Crappy T Lizzhe. I know that was wrong but :-p. I'm trying to be good on my '18 but it is difficult...
