Clearing a Flooded Engine
If the engine is primed for too long during startup, then it can become
flooded with fuel. When the engine is flooded it will no longer turn due to
excess fuel in the combustion chamber preventing upward movement of
the piston. Use the following procedure to clear a flooded engine:
1.
Remove the blue glow plug wire.
2. Remove the glow plug and gasket with the glow plug wrench supplied
with your model. A 5/16 or 8mm nut driver will also work.
3. Turn the model upside down and plug in the EZ-Start controller.
4. Push the EZ-Start button for several seconds to clear the engine
of excess fuel. Do not look into the glow plug hole while the
engine is spinning or you could spray fuel into your face!
5.
Turn the model over and reinstall the glow plug and gasket.
6. Reconnect the blue glow plug wire to the glow plug.
7.
Reconnect the EZ-Start controller.
8. Do not prime the engine. Pull the throttle to 1/2 throttle and push
the EZ-Start button. The engine should start immediately.
Piston stuck at “top dead center” (TDC)
“Top dead center” is the position where the piston is at the very top of
the tapered sleeve. Occasionally an engine can get “stuck” at this position.
This is most likely to happen on new engines during break-in, but can
also happen at other times. If the engine is stuck at TDC, use the following
procedure to release the piston from the sleeve:
1.
Remove the glow plug using the included tool or 8mm (5/16”) nut driver
and verify that the piston is at the top of its stroke.
2.
Use a flat blade screwdriver to rotate the flywheel. Place the blade of the
driver into one of the grooves of the flywheel and push down, turning
the flywheel counter-clockwise when viewed from the front. The flywheel
should turn, unsticking the piston from the sleeve.
3.
Put two or three drops of light machine oil into the glow plug hole to
lubricate the piston and sleeve. Do not use too much oil. It will hydro-lock
the engine. Verify the starter will spin the engine with the glow plug out.
4.
Rotate the flywheel so the piston is at bottom dead center and replace
the glow plug with gasket. Reconnect the blue glow plug wire.
5.
You should now be able to start
the engine with the EZ-Start.
