Engine: Mount the engine assembly to the
chassis with four 4x8 l-Head machine screws.
Place a small empty plastic bag between the
clutch bell and spur gear. Press the gears
together as you tighten down on the engine
mount screws. If you left the top engine mount
screws loose, tighten now. Remove the plastic
and check the gear mesh.
Fuel tank: Mount the fuel tank posts A and B to the
chassis as shown. Place P3 o-rings on top of each
post as shown, followed by the fuel tank.
Clutch: Slide cone collet and flywheel over crankshaft, followed by the pilot nut.
Secure the flywheel and tighten the pilot nut firmly. Place the clutch springs into the
groove of the clutch shoes. Align the clutch shoe and
spring assembly down onto the post on the flywheel
until the tip of the clutch spring snaps into the groove
on the pilot nut. Work in a counter-clockwise direction
until all 3 shoes are installed. Depending on the engine
you use, you may have to add up to 3pcs 5x7x0.2mm
shims before installing the 5x10 ball bearing.
These shims are used to remove extra
> movement of the clutch bell. Next, slide in order,
the bearing, clutch bell, bearing, 3x8 washer and
tighten with the 3x6mm cap screw. Make sure the
clutch bell spins freely on the engine.
The clutch bell should slide back
and forth on the shaft no more
than 1mm. Use the shims
to adjust this setting.
