Carberator Problem Update

[Steckmeyer]

On May 6 I posted:

We are putting the finishing touches on fixing up a Jubilee. She purrs just like the Ford advertisement says. As part of the fix up I put a kit in the carburetor. The gasket between the top and bottom castings sweats gas (I did tighten the four screws) and it appears that the little screen on the bottom of the bowl by the drain plug drips gas intermittently. I don't like leaks especially gas leaks. Any and all advice appreciated. Thanks

I followed all of the advice to no avail. I talked to the folks at external_link and they said to try one layer of Teflon tape on the float valve seat threads. "The latest seats are a little loose in the casting and my leak with modern gas" I was told. Tried it and still no luck.

In a moment of frustration I put the old seat and valve back in, adjusted the float and wallah! No leak. Looks like more crap replacement parts from India. BTW the "old" seat fit much tighter in the casting and the "old" valve is all steel.

Thanks to all that offered help.

I don't understand what difference it makes if the seat fits a little loose in the upper casting threads, as it is sealed by a hard paper washer. If you can tighten the snot out of it without the threads stripping, the gasket should seal it.

I CAN believe the off-shore parts may have been poorly made so the needle doesn't seal to the seat, though!

If the old needle and seat works, stay with it.

Are you saying that putting that old seat back in place solved the gasket "sweating gas", too?

I recently traded in my 41 9N that wasn't working and needed something like a resortaion for a recently reconditioned 46 2N with a loader. Many years ago I had rebuilt the carb on the 9N, with no problems. The "new" 2N has a seepy gasket between the upper and lower carb castings. I am thinking it needs a new gasket, but maybe not, if the gasket wasn't really the problem with your carb.
