The two responses, so far, are really typical of hand throttle use and I think others will further establish the pattern--a lot depends on the outside temperature, and using the throttle is a short-term activity.

Be aware, if you are retro-fitting a hand throttle to a later system, that you will need the micro-switch set up as well. When you pull up on the hand throttle, it not only pulls on the throttle cable but opens the micro-switch on the throttle body which permits the cold start valve to operate. On cold starts, you will need to pull up the lever (or hold your foot on the gas pedal) to operate the cold start circuit. You will already have a thermo time switch which overrides the cold start circuit when the engine is warm.
