Throttle and Choke Servo Installation
1. Gather the left and right plywood throttle and
choke servo mounting trays, the throttle and
choke servos and pushrod parts.
2 x 4-40 metal rods thread at one end
2 x 4-40 ball links and hardware
2 x Brass spacers
2 x 4-40 threaded solder couplers
2 x 4-40 threaded quick links
Note:
Servo mounting trays have been supplied for
your convenience. However, we have chosen to
mount the throttle servo into the engine box floor.
This allows for a fast and easy installation and pro-
vides a straight and precise throttle linkage connec-
tion.
2. If canister mufflers are to be used, install the
canister headers to the engine cylinder heads as
shown. Attach the throttle pushrod to the engine
throttle arm as shown. Layout the location of
the throttle servo and throttle pushrod as shown.
Ensure the servo and pushrod do not interfere
with the canister muffler headers.
