My neighbor adjusted my '26 NH carb float. %$#&@!
Gas pours out of hole behind carb.
Tap on carb gas stops.
Car runs for a minute and then stops.
Is the carb float hanging up on the side of the bowl?
I would appreciate any suggestions (other than getting a new neighbor).
Oh, boy. I was hoping someone better than I would have answered this by now.
So many possibilities. So many things to maybe check.
The first thing I would check is the float valve itself. There are many choices for these. Many different opinions of what is best. I am glad that new valves are made. But I only use original type all steel (triangular shaped) valve in original brass body/seat. I DO NOT use rubber tipped, floating ball, (I don't even know how to spell "Grose"jet?) or any of several other replacement float valve. Original type I think are still available, however, I have always found I had a repairable original.
Many of the odd replacement types are notorious for a variety of problems with either reduced flow into the carburetor (they were designed for higher pressure fuel pump, not gravity feed), or overflowing because the model T float doesn't put quite enough closing pressure on the valve (again because the modern valves are designed to work with a moderate pressure pump, the float also must be designed to shut off against that pressure).
Again, first thing to check is what type of valve is above the float.
The Holley NH is a simple and very easy to work on carburetor. The WORST thing about working on them is getting that float valve seat to come out of the cast iron body. If you do need to remove it? And it does not come out easily? Do not force it. Ask here first.
Maybe more later. Gotta go.
Drive carefully, and enjoy, W2
The float could be hanging up, as you say, but more likely it's the valve. What kind of valve is it? Some of the current replacements are notorious for this kind of problem.
