Pin holes in Air Cleaner Cup
I removed the air cleaner cup on the '50 SA I am trying to get running so the owner can sell it. After cleaning out the gunk, I saw 3 tiny pin holes in the bottom. I don't have the ability to weld, so my question is, can JB WELD be used to fill those holes? Or are there suggestions for another repair method?
The pinholes are circled, but you need to click on photo to enlarge and see...sorry it's not more clear.

JB weld will be fine or any epoxy.

Re: Pin holes in Air Cleaner Cup
You just have to get it really clean around the holes. Put the patch on the inside.

That would be the way to do it. Jb weld on the inside of the cup. Good as new. Resist the urge to sand it down so smooth that it’s too thin.
Welding it would be tricky for anyone as it’d be hard not to blow larger holes in the thin metal making it a bigger mess.

Soldering would also work well.

Re: Pin holes in Air Cleaner Cup
Don, are you talking about using a soldering iron/gun or a propane torch?

Re: Pin holes in Air Cleaner Cup
I believe a torch would work better in that situation.

Re: Pin holes in Air Cleaner Cup
I would do the epoxy patch, then use a gas tank sealer, Red Kote or similar, to coat the bottom1/3 of the cup.
My experience is that once pin holes appear, a patch only holds until another hole develops.

I have an excuse. CRS.

You are right about more pinholes being possible...since the current ones are simply where the metal is thin.

Re: Pin holes in Air Cleaner Cup
If you heat epoxy with a heat gun, it will get thin and flow. You could then get it to flow around the bottom of the cup and fill like a coating. Because the epoxy is thin, it will want to flow into the pinholes so before you start pouring epoxy, put some blue painters tape on the bottom of the pinholes. Let the epoxy harden before removing the painters tape.

That's a great tip. Thanks for sharing it.

Re: Pin holes in Air Cleaner Cup
Do you recommend a particular epoxy? I go cross-eyed standing looking at all the different choices!
