I ran across a Kingston carburetor yesterday and the guy says it was a 6 ball. I don't guess I have ever heard of one let alone seen one. It appeared to have a flange that would bolt up to a T intake and has what appeared to be an accelerator pump. Any idea if this is really a 6 ball and what might it be worth? Just curious. Solid brass to boot!
I believe they were used for very short time on the 1912s. A nice one sold for 840 a while back.

Very rare. It's not an accelerator pump, it presses the float down to flood the carb with gas in place of a choke.
Thanks for the info.
I do have another question. What function did the balls provide for these carburetors and why were there different ball counts?
As the speed increases the balls pull off the seats allowing more air to mix with the fuel to lean the mixture. Fewer balls are cheaper would be my guess.
Stan, overall, how did they perform?
I wish I knew!! I've never seen a real one, let alone have one to try. My guess would be they run quite well. The 5 ball runs very nicely but the early ones with no choke can be hard to start is what I hear. Cheaper and cheaper and with fewer machining operations would be the reason for going to the less complex carbs. If you look at something like this and then the NH you can see where Ford was saving money. These carbs probably were costing Ford 6-10 dollars each, 15 years later the NH was 30.5 cents with very similar performance.
