I have a carburetor bowl with a hairline crack in it and obviously leaking. This particular part is very difficult to obtain.
I am looking at ways to repair it.
Thought about solder, but as its made of crap metal, it is likely to melt at a similar temperature to solder. I have tried an epoxy petrol sealer, but that leaked after about a year.
Also thinking that a little bit of tank liner solution may work, only need about 10 ml.
Any other options available??
Appreciate any thoughts

Unfortunately Oddjob, it is not a Honda item. Its for my Suzuki Rebel and I have been chasing after one for about a year. Seems to be a one carb only bowl. Even the 250 Hustler of the same year has a different one. Hence the repair option.

Fringe idea, but with possible potential.

Maybe use a small thin copper plate inside the bowl soldered to it, won't be pretty but obviously unseen.
Play with a hack float bowl to assess potential first.
He pronounces "solder" in a wierd way though :)

Possibly try with some silver solder as the patch material, planished into a thin plate to allow it to accept heat quickly.

Thanks for the replies gentlemen. Gives me some good ideas to try. Copper plate may just do the job on its own as it is only a hairline crack, but enough to cause drips from the carb

If its such a fine crack how about some really good cleaning in the area and Hondabond a layer of kitchen foil in place?
