Hi folks,

I see that there have been some more eyeballs on this thread. So, here is the latest.

I used Permatex 85420 sealant to fill the bottom of the valve assembly. Let that set for a little over an hour. Perhaps I should have let it cure overnight, but I was in a hurry. Reassembled the valve. Checked for leaks while idling for 10mins. Then took it for a 26 mile drive, checking it at 13 miles and at return. No leak, no dribble, no hint of any gasoline exiting from the valve at all.

At the end of the drive while the engine was still piping hot, I used a spray bottle filled with water to do a very cheap steam clean of the carb bodies, carb catch plate, and manifolds. Then re-filled the bottle. Trying to get gasoline residue off of these and other areas that have been showered with gas splatter.

I could not smell any gasoline during my test drive.

So far, so very good. I will look into if and how I can get a new needle/diaphragm, in the not too distant future -- without buying a new carb. This repair was $10USD.

I hope this has been of some help.

See a couple of pix in my gallery.
