Holley 94

Hello good people. Does anyone know if the idle jet(H32?) has a 3/8-24 thread? Thanks in advance.....

If you mean the actual idle tube/jet that screws into the bowl side of the nozzle bar, it's a special 1/4-32 thread.
If you mean the brass fitting (air bleed) in the middle of the nozzle bar it's also a speacial thread 3/8-32
Main jets are also 1/4-32, and there are taps on EBAY for 1/4-32.

This is the jet in question....

The idle tube for the 94 has fine thread 1/4-32. The Stromberg idle tube has the same appearance but with a courser 1/4-24 thread.

Ok, so this won't work. Anyone know of an equivalent, but with a 3/8-24 thread? Thanks all.

Would it be worth explaining what you are trying to do?

Some pictures might help.

Unsuccessful finding replacement main jet for alloy, Model A updraft carb by Simmons. I've attached a photo. Holley 94 jet looked similar, but wrong thread size; needs to be 3/8-24.
