Obviously this is a Kingston carburetor, but does anyone know which type Model L it is and know any information about the tickler button on the top of the bowl?
I have asked Stan, but he has not worked on many of these carbs and is unsure.
Can anyone help?

Going by the shape of the inlet, I think its the original Model L used in 1915. I could be wrong.
It is an early one, around the end of 1913 model year. Not too common!
The 1915 version has no tickler.
Was it used in regular production? To my unpracticed eye it most closely resembles the 1915 L shown in the encyclopedia, except for the tickler. It's quite a bit different from the 1913-1914 Y shown in the book. Rodda shows one like this on Page 17 of Volume I, and identifies it as similar to the L except for the plunger. It also differs from the L as it has a non-flared inlet. Rodda suspects it may be aftermarket. Maybe Russ Potter could tell all about it.
Not sure if you're asking what the "tickler" button is for, or not. Just in case, it's used to hold the float down enough to flood the carburetor just a bit. Enough to create a puddle of gas near the venturi, at the bottom of the "U" passage. Then, when you crank, that slug of gas gets sucked up and gives a little extra charge, presumably for easier starting. It's kind of unneeded since the carb also has a choke. My Model N and my '12 Overland both have this feature, (and they don't have a choke).
Most 650 Triumph motorcycles have the tickler and a choke. You will kick forever if you dont ticker the carbs and get the smell of gas on your hand. Scott
