4. Place the spinner cone over the prop so that the blades of the prop
fit into the notches of the cone. Replace the two spinner assembly
screws. The cone should sit flush against the back plate.
There are Several Simple Steps to Starting the Engine
1. Install a glow plug. The glow plug threads into the top of the cylinder
head. We recommend the O.S. #8 glow plug (OSMG2691).
2. Remove the fuel tank pressure line from the muffler.
3. Remove the fuel line stopper from the fill line and insert the filler
nozzle (not included) or remove the carb line.
STARTING THE ENGINE
4. Fill the tank almost to the top. Leave a little air at the top of the tank.
Excess fuel will flow out of the tank pressure line when full.
5. Replace the fuel lines.
6. Open the high-speed needle valve 3 turns out (counterclockwise) from
fully closed. The high-speed needle is sticking out the left side of the engine
(looking at it from behind the prop). If you have previously run the engine,
keep the same needle valve setting that you used on your last run.
7. Prime the engine by flipping the propeller counterclockwise with
the intake choked. Stop when you see the fuel reach the carburetor.
This will take approximately 3-4 revolutions. DO NOT ENERGIZE
THE GLOW PLUG DURING THIS STEP.
8. Secure the glow starter onto the engine's glow plug.
