Replacing the pot metal float bowl with a new bronze version, but can't figure out how to remove the main jet from the bowl assembly. Connected to the bottom of the main jet or nozzle there is a dashpot piston which is larger than the jet tube and so prevents sliding the jet out from above. What I need to know is how one disconnects the piston from the jet.

The piston has two circular indentations on either side of the hole the metering pin goes through, and the jet itself has flat spots so it can be held by a wrench. Thus it would seem logical that they screw together, but I'm not sure what tool to use on the piston and am wary of applying much force. Can anyone help?

In this diagram the main jet is identified as Part B, and just below spring E is the dashpot piston through which metering pin P goes.

Best way to remove the jet is to make up a special tool that interfaces with the two small blind holes / indentations drilled in the face of the jet.

Pic's attached of one I've made. The jet unscrews from the casting, it has right hand threads, CCW rotation to remove.

thanks for the drawing and input, I have removed everything from the carb and checked all ports, other than a small crack in the throttle body, I see nothing wrong,
I have a replacement throttle body and I am hopeful that will fix my issues.
Any other suggestions or ideas are welcomed!

Thank you 32model901. Very helpful indeed!

Sherlock, glad I could help.

Some dimensions of the working end of the tool, in case you want to fabricate one.

Thanks again 32. What did you use for the pins? I'm thinking the butt end of a 1/8" drill bit?

I used short pieces of music wire.

Drill rod would also work.

Or the broken off ends of a size 50 drill would also do the job.

Drill the depth at least 3X the pin projection, or about .300 deep. I press fit the pins in, if this is a problem drill the holes slightly larger and use thread locker, Loctite 261 or equivalent to hold them in.

Thanks again!
