JB Weld it?

if its on a water passage I wouldn't. See if it can be welded if so go for it if not, wait till a good one pops up on ebay.

JB weld is for holding your broken tail light together. it is not for engine component repair unless maybe the vanity cover over the carb.

either fire up the welder with a high-nickel rod and weld it, or get a new one.
