have to pinch the fuel line closed for several seconds before the
engine stops.
2. Completely empty the fuel tank. Use your fuel-dispensing bottle
to suck out the old fuel. Do not mix the old fuel with your fresh
fuel supply. If you leave fuel in the tank, transporting or handling
your T-Maxx may cause fuel to run into the engine.
3. With the fuel tank empty and the throttle at the idle position, try
to start the engine. The engine will most likely start and run for
a few seconds as it uses up any fuel remaining in the engine and
fuel lines.
4. Once the engine stops, clean the outside of the engine with
compressed air or spray motor cleaner. Once the engine is clean
and dry, remove the glow plug power wire, glow plug, and air filter.
5. Open the throttle fully and spray a one-second burst of WD-40
into the carburetor and into the glow plug hole (Caution! Wear
safety glasses to prevent spray from getting into your eyes). If you
are using after-run oil, follow the manufacturer’s instructions.
6. Place a rag or paper towel over the engine to catch any WD-40
or after-run oil that may come out of the carburetor or glow plug
hole.
7. Connect the EZ-Start controller to the model and spin the engine
for 10 seconds.
8. Remove the rag or paper towel and repeat steps 5–7 two
more times.
9. Clean and re-oil the air filter so it will be ready for use next time.
See page 19 for air filter maintenance instructions.
10. Replace the glow plug, reconnect the glow plug power wire, and
reinstall the air filter.
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
counterclockwise 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 the gasket. Reconnect the blue
glow plug wire.
5. You should now be able to start the engine
with the EZ-Start.
Top Dead Center
Bottom Dead Center
Denatured alcohol (available
from home centers and
paint supply stores) in a
spray bottle is an extremely
effective cleaner. Be sure
to wear safety glasses and
gloves when working with
denatured alcohol.
Be sure to follow proper
maintenance and storage
procedures to avoid damage
to your engine and other
components of your T-Maxx.
Don’t put the fuel from your
tank back into your fuel
jug. Dispose of it properly,
following city or county
regulations.
Always wear eye protection
when using compressed
air or spray cleaners and
lubricants.
