The linkage animates a few cycles, and the data is given...

a1 is the left throttle angle
a3 is the right throttle angle

min and max are the respective differences between the two throttle levers over a whole cycle, in this run the worst case is a difference of -2.92 degrees.

The 'graph' ahhemmm..... shows the difference in throttle angle over 2 and a bit cycles, note the cycle starts with both throttles fully closed.

By changing the position of the shaft at x3,y3 (moving horizontally only) and rotation the shaft (i.e. moving x4,y4 and x7,y7) you can optimise the geometry for a minimum difference in throttle angle.

Im still optimising........
