Does anyone have dual throttle controls with their Corvair. I am using a MA-3 carb, and a center stick. I plan to have a throttle control for both the pilot and passenger side. I am thinking that I can just hook two cables to the throttle control arm on the carb and they will simply work in tandem? Am I missing anything here? What have others done so the the passenger can act as co-pilot?
I plan on doing just what you describe - two throttle cables connected to the same carb throttle arm. Several years ago someone described using that exact installation. That person removed the throttle friction adjustment guts from the co-pilot throttle cable handle. That way only the pilot friction control can be adjusted and the co-pilot unit is always just along for the ride. That person reported good results with that type of installation.
The two cable ides strikes me as being a better solution than the dual throttle arrangement that comes with the kits - too many pivot points and connections points.
I designed my own dual setup in 2014. I also have the MA-3 carb. I made mine with a single cable bought off the shelf from Aircraft Spruce and fabricated a simple bellcrank system that has been totally reliable. I would send you pix of all this, but the photos are on my computer, which this one is not. I'll try to add the illustrations to my page when I get home .

Thanks David. I will look forward to seeing that.
Joe, I have added some pix to my page.
my email is email@example.com if you have any questions. (A.C. Spruce part numbers, etc)
I have the same carb and stick configuration. Also wanting to know how others have been doing their dual throttle setup.
