Uh oh...... I broke the threaded section off the main jet. Spent a couple hours online looking for another but all that comes up is the adjustable needle. Am I S.O.L. or can I JB weld it back in? The needle seems to seat firmly in whats left of the threaded section of the jet still stuck in the carb.

Darn it!! That’s the pits, if the needle seats against it ok, I’d try it. Nothing to loose at this point.

This seems to not show that jet too.

Zenith series 22 carb

Digging through my cat part books didn't show a jet there. Maybe it is considered part of the main body?

Welcome to the forum Skoop. try jets for other brand carbs, someone auto parts knowledge at a local auto parts store should be able to help. If you are able find a jet that will fit but has a slightly different orifice number (size) on the side of it don't worry, one number either way will be better than risking a patch on the broken jet.

Thank you for the responses, gentlemen! However, it is a Zenith 261-8 model carb. Series 11752. Ive tried a few auto parts stores to no avail. And any searches for the jet itself just bring me to the adjustable needle. One was not included in my rebuild kits and the few carb sources Ive spoken to say they cant help me. One would think jets would be a somewhat standard replacement item.

Odd duck I have never seen. I don't see that main jet adjuster anywhere on this diagram.

What series D7 are we working on?

The link to carbkit source does no relate to a 261-8 carburetor that cat used. If you click on the replacement carburetor link, you get a view of a correct 261-8.
Using OM's list of Zenith part numbers, the main jet c52-32-27 converts to Cat no. 9F2902. Which if you go to machinerytrader.com and search for the cat number, there are a number of sources.
Appears that the main jet is common to most updraft pony carbs on Dw 15, 20, 21, D7 17a, D8 14a, d9 18a 19a.
