I rearranged the ball link on the carb, and the mounting position on the horn for a straighter fit.

The EPA for the throttle servo is set next. You want to make sure the servo travel enough just enough to fully open the carb. You also want to to close the carb fully under brake, and make sure the gap you've set is correct. If the servo travels too far under braking, you can see the engine being pushed.

Key points here, idle gap is set with the restrictor off (Usually .5 -1mm.) However the carb only have to open past the opening with the restrictor in. Also roll the car under full braking to make sure the brake actually works. You might have to heat the carb a bit to remove the restrictor safely.

Lastly set the EPA for your steering servo. Adjust the EPA so it turns to the position you want to set it at, but not travel so far that the servo is still working when you've already hit the full lock position.
