D4 5T Zenith Carby

Thanks Bruce, I have emailed carburetor shop asking if that jet comes in the kit. I think I bought one from them about 5 years ago , but my memory has gone from smelling too much of this carby. Their codes rang a bell. Thanks for the image. It shows the soft plug I was asking about is lead. There are a couple of odd elbows coming off the carby in your image that I don't seem to have. See my pic in original post. Thanks again, David

The carburetor shop cannot help with the main jet adjustment screw. Any other sources ?

Thanks for the pics Eddie. It is that main jet #14 in your first pic. I cannot braze it back on that straight.

Is it hollow all the way up? The top section does not have to be hollow, so put a short piece of rod or wire in it to align it perfectly and then silver solder it up.

If it's solid, I would try to braze it and then straighten if necessary, or perhaps have one made on a lathe.

It is hollow at the seat section with a pin hole in its side that accepts fuels in and drops it out its base to feed the carby. Ie: screw it down and less fuel gets into the side pin hole. So too complex to turn one up .

The top is solid, where it has snapped , but brazing it that straight as needed ?....... I guess length can vary as the screw can cope with that.
