FOUR-STROKE INSTALLATION
 Step A
You will need to drill the firewall to install the pushrod tube

firewall in a location that aligns with the carburetor arm of
your engine.
 Step B
Remove the engine from the mount and drill a 5/32-inch
(4mm) hole in the firewall at the mark made in the previous
step. Use medium grit sandpaper to roughen the ends of the
pushrod tube. Slide the pushrod tube into the hole so it is
flush with the firewall. Use medium CA to glue the pushrod
in position.
