Is it normal for a Tillotson float arm to wear/create a dimple from the needle valve so quickly?
The carb was recently rebuilt on this Model A that I bought a few weeks ago. After getting it home, it started dumping gas from the carburetor. I took it apart and found that the rebuilder set the float at 1-1/4" instead of 1", causing the float to drop so low that the needle valve dropped too far and put it in a bind. Wouldn't let the float come back up. The end of the needle valve that contacts the float arm had also put a decent dimple in the brass. I took some sandpaper and smoothed that whole area of the float arm to remove the dimple and reinstalled.
Now, I have the carb. off and apart because it's leaking at the gasket (housing is slightly warped). During disassembly, I noticed that a new dimple is already forming from the needle. Is this normal for it to form this quickly? (I have only put 5 miles at most on it since sanding it smooth.) Wouldn't this eventually wear through at this rate?
