I have repaired ZS carburetor bodies with alumiweld. It is workable
with a standard propane or butane torch so it works at lower heat.
The manufacturer claims you can repair pot metal also, but I have not
mastered that technique - the correct temperature for pot metals is a
mystery to me - and probably to the makers too!
