carb problem

I was in the process of taking apart my carburetor in my 1989 jeep wrangler 4.0 to clean out the jets, and while trying to removed the hex screw that holds the electronic choke cable to the pin in the carb, the head of the bolt snapped off with the remainder of the bolt in the carburetor pin. Does anyone know where I can find one, order one, buy one, all the junk yards are cleaned out in the area and I cannot find one online. I really don't want to install a manual choke or purchase a new carburetor just for the pin!!!

Please advise

Put up a pic. If I don't have one, someone else probably does. I am not real sure which part you are referring to.

I also am not real sure what pin you mean, but it almost sounds the the choke rod. Basically any broken off bolt can be carefully drilled out and rethreaded. When I drill them out, I get a bit slightly smaller than the bolt and drill it slightly off center so I end up with a crescent moon shape left, normally barely touching one small area of thread. This crescent shape can be backed out with an easy out or small screwdriver. Normally I don't even have to redo the threads.

OK, the only hex screw I see on the whole carb is in the end of the choke plate shaft, holding a rod bracket on. I had to look at my installed carb as neither of my backup carbs has one in it at this time.

Just drill out the broken screw, tap to clean the threads, and install another screw.


eta: there is no need to remove that screw to access the jets, un hook the choke rods and just remove the top cover next time.

Yes, it is the choke rod. I've tried to drill it out but had no luck. thought it would be just easier to get a new or used one somewhere but finding that difficult. Any help would be great.

thanks.

It should be the choke rod that the butterfly plate is attached to. In this pic it has a slotted screw with a shake proof washer holding the rod plate onto the shaft. He needs the shaft and screw from what little he is telling us.

eta: the pivot axle that the choke plate itself is on.

And from what I can tell, that is not a service part. A junk carb or a carburetor overhaul shop is your best bet. I do not have a spare top assembly, and this is how you will find one. Sorry.
