Carb drain plug

[rikscubby]

I’m about to reubuild my carb and wondering if I need to change the drain plug out? How does this plug come out?

Original drain plugs were threaded.

Thanks Bill. From the pic you can see the metal was what appears to be pounded over it. Is that normal or best to leave as is and not change it out?

It is a felt disk that allows the throat area to drain if flooded. Just clean it with carb cleaner and leave it in place.

Sorry, I was referring to the drain plug on the right in your photo. Don has got you covered for the plug on the left of the photo.

The cupped washer with the hole was originally staked on four sides to keep it in place. You can see one mark at the bottom. If you must remove it (if you can see light through a hole in the felt), you'll need to cement it back in with JB or another epoxy. Almost impossible to restake. Do as Don said.

Hi,
Below is a pic from TM Tractor of the bottom of a Cub IH carburetor. You can see the staking marks at the round cover.
The hole has a filter material in it, and lets excess gas drain out, if gas gets into the air intake, like was said above.

Thank you all. Very helpful and it’s much appreciated!
