Re: Yet another question for Owen D

Terry, I don't know how much of the hand throttle assembly you have, and these pictures arent' the most informative. It's one of those things that, when you examine it, it's function is immediately obvious, but it's not that easy to describe. But here goes a try...
In the first picture you can see the arm perpendicular to the steering column; on it is a bevel gear that matches one at the base of the column and it's driven by the hand lever under the horn bezel. The spring and bolt are to adjust the friction clutch (red washer) such that the throttle lever will hold it's position. You can also see the nickel-plated linkage rod heading rearward.
In the second picture you can see where the linkage rod attaches to the arm which is attached to the cross-cowl shaft rod from the accelerator pedal to the carburetor. What's hard to see is the last 2 inches or so of the arm; it has a stamped steel extension and tab which allows the hand throttle to operate the link to the carburetor, but also swings out of contact when you press the accelerator pedal further so the accelerator can provide more throttle but will return to the position set by the hand throttle when the pedal is relaxed.
Clear as mud? Let me know - I can try to take some additional pictures and/or try a new description.
Hmmm... I see some surface rust beginning to accumulate on the nuts and bolts - time for a good cleaning!
