Brief Description: Throttle cable lever (beginning)
|
|
The SeaRey throttle lever would pull the cable when moved forward, and push the cable back when going to idle. The Viking engine needs this to happen opposite… pulling is going to idle and pushing is opening the throttle, so I created a bracket to attach to the lever, where I could attach the throttle cable to some point at the bottom, in order to reverse the action.
There’s only 1.75” of travel between idle and full throttle, so an added benefit to doing this is I can attach the cable at a point on the bottom that will only travel that amount, but ensure the top of the lever has a much greater range of motion… for precise control of the throttle.
The center console has a hole these levers protrude through, and you don’t want your lever to try and travel more than that hole, because it’s just going to hit it and start damaging the console, so the first step is to put the console on and set the absolute range of motion with the setting screws at the bottom of the throttle lever.
Now I cut about 10” of an aluminum bar, and drilled for the two top bolt holes. Spacers are needed between the bar and throttle lever, and six AN3 washers is just about right. Once that’s attached, I took a metal ruler, and found the place on the bottom that traveled just over 1.75”, letting the metal of the ruler mark that for me. I drilled the bottom hole to attach the throttle cable.
