Do these Primary Rods EXIST or are they just TYPOs?
« on: February 20, 2026, 09:48:20 AM »
Doing some Quadrajet research and I've found some Primary & Auxiliary Rod numbers listed in the 9C's that don't show up on any lists or internet searches. I hope someone has dealt with these before. Thanks for any help given.

      P. ROD#              9C-              CARB#
1.)  7043537             2012            7045193
2.) 17053335            3091T          17058512
3.) 17053339            2014-A         17057533

   AUX. ROD#            9C-              CARB#
4.) 17052814            2012            7045193/230
4.) 17052815            1045            7045548

Interesting how many were Cadillac carbs.

Just found the answer to question #1. I just had my hands on a Primary Rod marked 37J from a 7045193. Since the 9C calls for a 7043537 and the rod is marked 37J(which falls inline 7043536 = 36J & 7043538 = 38J) I feel pretty good about this one.

While question #4 asks about the Auxiliary Rod and this one is marked 35B. If we assumed it is the original that would be a 17052814?
No way to know for sure, but this carburetor was not a reman and it looks fairly original to me.

Let me know if you have any evidence either way.

Just found the answer to question #4 about the Auxiliary Rods. It's in a 9A-100 catalog dated 1988.
It lists 3 Aux. rods as:
                                  17052814     35B
                                  17052815     52B 
                                  17052816     50B

So that only leaves the two Primary rods.

The 17053335 and 17053339 would be 35L and 39L as the L series rods starts with 170533xx.

Kenth,

I found those listed in the Big Book 9C's, but have been unable to verify that they actually existed, short of buying an ebay carb with those and hoping they were not changed somewhere along the way. That's how I verified the ones in the 7045193 lol.

Thanks for the information!
