Leaky Mac

[guiness1976]

Hi everyone. Ive been lurking on the sight for many months and finally registered. Thanks for help I've already received in the archives.

I recently bought a Mac 1-53 off ebay. It started and ran rough so I disassembled it, cleaned, reset points and rebuilt the carb. I put a nice coat of Mac yellow on it and now it runs great. My problem is the split gas tank. When I reassembled I cut new gaskets and used a Permatex hi tack gasket sealer that claimed to be gas resistant. The sealer is red and now the gas is seeping out and bubbling up under the paint. When I did a search I got some mixed answers. Some advise a dry gasket, others advise special loctite.

Does anyone have a good method for sealing these tanks?

I bought some stuff in a tube. It is called three bond. Best stuff for oil or gasoline I have seen. Mike

The threebond sounds thick like JB Weld. Is it? Thanks for the reply.

No not like JB Weld.

Mike, did you use the Hylomar(blue/white tube) or the Case Sealant(yellow/white tube)

I did not know there were two different types. I have the yellow/white tube. It seems to do what I need and does not break down from oil or gas. I have even fixed a couple of those cheap huskys with the leaky, oiler, rubber parts. Mike

Thanks for the help guys. I will try the case sealant.
