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.
