Broken how? A carb will most likely not run correctly if it is missing a jet. They regulate the gas flow to a carb, and without it, it probably won't work...or at least correctly. Why don't you order a replacement jet for the carbs?

Thom if you look at the pic the one on the left has a jet on the post, the one on the right does not have a place for the jet.The housing at the mounting hole broke.

it could be the jet is located at the bottom of the center post while the old one has its jet on the side. There's no such thing as a carb having no fuel jets, I mean as far as this old carbs are concerned.

The jet's in the bowl screw.
​Compare the #s and see if they are the same.

The carbs using the bowl screw were used in the early 80's
Measure the venture or throat of the carb.
They must match.

​The bowl jets came in 4 sizes.
Pretty important that they match what you have.

If they came in a set?? Pretty important to use the whole set.

I am using the whole set. The Throat is the same size. I believe the jets are the same size, and the little tubes in the stem are the same. I'm going to try them today.
