Any suggestions as to why these parts were added and what is the purpose for extending the throttle arm upward? Is the throttle arm installed correctly or should it be inverted before tightening to the shaft?
Thanks for any help.

Question About Holley G Carburetor
I recently got a Holley G carburetor with an unusual (at least to me) Throttle lever setup. It has the Dec 22, 1914 patent date on the top. The extra part is 1 1/4" tall and has a label that says "Apex Elec Mfg Co, Made in USA, Chicago". It has a thin slot that can be seen in the first picture and a similar slot in the shaft that is only about 1/4" tall. I'm not sure the purpose of these slots.
Any suggestions as to why these parts were added and what is the purpose for extending the throttle arm upward? Is the throttle arm installed correctly or should it be inverted before tightening to the shaft?

Re: Question About Holley G Carburetor
James, effectively that part extends the length of the throttle shaft. It also allows the linkage to be rotated on the shaft for a different orientation. On US made carburetors for model Ts that are fitted to RHD cars, the linkage has to be repositioned. This is usually easily accomplished, as the throttle arm is usually just clamped to the shaft like the one shown in your first photo. The standard short shaft still carries the idle stop arm, but the shaft needs to be longer to allow the addition of an adjustable throttle lever. Your attachment allows this, but I have no idea why it has the idle stop in the top piece.
