I just sold my stock carb and DJ kit.

More must be around. The brass jet is down in the pot metal carb. It may be hard to solder the jet shut. The pot metal carb may rob all the heat to solder the brass jet inside it.

It may be easier to replace the carb, but I would try solder first.

FWIW,
The bit is also referenced and or sold under a designation of #77 as well..

 

These are both capital ideas!!

 

Just be very topical about it. Try to apply the solder/jbweld/plastic tapered plug so that it sticks to the top part of the jet. That way, the worse case is that the blob of solder falls out into the carb bowl and then the next time you try and start it the choke will be too rich.

Remember when drilling the new hole in the new material that the drill bit may try and fall into the old overbored hole which may be off center. That could cause the bit to break off which could be worse than anything.

Earlier I said to braze but my terminology was poor. I believe solder is more appopriate term since you aren't melting any base metal into the jet.

 

I WOULD NOT use any method that requires enough heat to melt solder or brazing material. The carb is likely to melt. Go with the JB Weld, safer to use and easier to get it where you want it.

Brewster, would using the right solder...a low temp type...really put the carb body pot metal at risk? Granted, you have to use some judgement in how and where you heat the solder and jet, but I'd be surprised to see the carb start melting. Yes, jets that have been soldered and then drilled are normally out of the carb body when soldering the orifice closed, but does carb body pot metal have that low a melting point?

This discussion did get me to thinking that judicial application of heat via a soldering iron might actually allow removal of the starter jet. I wonder about that. Brewster, have you seen any sources for the starter jet itself? I haven't, but I thought maybe someone has...or any techniques for removing a starter jet.

 

You should be able to find some fishing line or a brissel from a nylon scrubbing brush that has a diameter of .018".
Embed this in the JB weld. You should be able to pull it out after it hardens and have the correct size hole.

 

The body of the carb is a BIG heat sink. It would be very difficult to get the jet hot enough with a soldering iron. Any other heat source would not have a controlled temperature.

I would suggest that Sudco be contacted. They carry Keihin carb parts, but do not show the CVK.

Has anyone actually removed the pressed in starter jet yet?Just curious.

 

not that I've heard about.
