I’m suspecting that my (MFI) throttles don’t open up completely when the accelerator pedal is completely depressed. The rod at the accelerator pedal is at its longest and the stop is at the bottom of the pedal board, but there’s not that much travel on the pedal. If I put a weight on it to keep it at the bottom, I can move the throttles at the engine quite a bit further still.

1. Should the linkage be adjusted such that the throttles at the engines are just at their maximum stop position when the accelerator is fully depressed? Or could this be beyond the maximum opening?

2. It looks like the linkage needs to be adjusted so the pedal ends up higher, so it has more travel and can therefore fully open the throttles. Is this achieved by adjusting the rods to the left side of the gearbox underneath the car?

What I’m reading is that this can be very hard to set up correctly, so any tips would be highly appreciated!
