􀀀 Step 20
Use a 1.5mm hex wrench to remove the throttle
arm from the carburetor. Slide the arm onto the
throttle pushrod Z-bend then replace the arm on the
carburetor. Set the arm so the Z-bend is just clear
when the carburetor barrel is in the fully open position,
then secure the arm in position with the 1.5mm wrench.
After installation you may need to use pliers to make a
slight bend in the pushrod for smoothest operation.
􀀀 Step 21
Now is a good time to set the throttle travel before the
cowl is installed. Use your radio to move the throttle
servo to the fully open position. Move the pushrod
forward to open the carburetor to the full open position
and use a 1.5mm hex wrench to secure the throttle
pushrod in the EZ link. Now use your radio to check
operation of the throttle throughout its range and make
any adjustments to the pushrod or servo travel volume
as necessary. Using the equipment and dimensions
shown here, we found ATV values of 100% for high,
and 110% for low throttle settings to be ideal.
