Farmall A Idle Jet

Sun Oct 24, 2010 1:00 pm

I recently picked up a Farmall A with a very clogged up carb. The carb is a Zenith. I thought it was an 8808, but it turns out it's a later replacement 12613A (IH Part Number 375560R91). I ordered a kit for an 8808 and disassembled the carb for cleanup. I pretty much destroyed the idle jet on removal. There was a similar jet in the 8808 kit, but the screw size is a little smaller. Searching the internet, I've only come across basic carb kits for the 12613 and those do not include the idle jet. Does anyone know what the correct idle jet is for the 12613? And where can I get one? Thanks!

I have obtained hard to find carburetor kits and parts from the above business.

I&T, IH-8 manual lists the A's Zenith carburetor as # 161X7-9752. Other suggestions: Carter - Grunwald, or your Case/IH dealership.
