The Ford Barn

I wonder if it could be lapped in like a fuel valve.
For lapping, I use rottenstone powder mixed to a paste with paraffin oil. It is VERY fine grit. Works super for polishing nickel plating also. Pumice stone powder is the next coarser grit. Available at most paint or hardware stores.---Bill W.

Following recommendations here on the barn, I gave the original brass valve a 40 - 50 turns with fine valve lapping compound. No leaks in the two months since then.
