DO NOT USE THE TWIST GRIP ON THE TILLER OR REMOTE CONTROL THROTTLE. Disconnect the remote control. Turn the vertical shaft on the starboard side of the motor so the magneto base touches the stop. The roller is still against the cam and the butterfly valve is almost half throttle. NOW you place the collar and tighten the screw. Further advancing the tiller grip pushes the collar to fully open the butterfly valve in the carburetor. . . 🙂
