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 both
high and low settings to be ideal.
􀀀 Step 14
Use a cutoff wheel in a rotary tool to cut 3 1/4 inches
