4160 Holley Carb Leak & JB Weld

[davekro]

Has anyone had success (or not), using JB Weld on a carburetor leak? If the seal does hold, obviously I will check it regularly when I test drive it and occasionally afterward. I'm just curious if this could/should be considered a long term fix, or if it may be too risky?

the story...
I just got my Holly 4160 carburetor back from a 'friend of a friend' mechanic who installed a rebuild kit for me. The 1/2" plugs (other models had bowl adjusting screws here) on top of each bowl now leak. I found out that this is a non serviceable part, so I'd need to buy new bowls (so much for going the inexpensive route), for the correct fix.

But, with nothing to lose, last night we applied a generous amount of JB Weld epoxy over both plugs. I'll either test it tonight (18 hours cure), or wait until tomorrow (36 hour cure) before retesting.

Thanks for sharing any experiences with JB Weld, or opinion on this 'fix'.

I have used JB weld on my exhaust manifolds with great results. Still ok. I don't think I would be looking for that kind of fix when the result is leaking fuel on a potentially hot motor. I have seen a couple of boats go up in flames over my years on the water andI don't think anything is as frightening as when you have nowhere to go but over the side and wait for help. Just my thoughts.
