STEP 4: SETTING THE IDLE SPEED
The idle screw regulates the throttle opening to control the idle
speed. The throttle opening at idle should be set as shown in the
drawing. The opening should be 1 to 1
1
/
2
millimeters at the widest
point in the opening. The engine may not idle well until it is
warmed.
STEP 5: LOW SPEED MIXTURE SETTING
This screw meters the fuel at low speeds. The low-speed mixture
screw is located in the end of the carburetor, inside the throttle
arm. This screw controls how much fuel enters the engine at idle
and low throttle. This adjustment will smooth the idle and improve
acceleration to mid-speed. Make this adjustment with the throttle
closed, after setting the idle. To get the low speed mixture into the
correct range of adjustment, turn it in or out until the head of the
screw is flush (even) with the end of the throttle arm assembly. This
will be the starting point for future adjustments. Fine tuning the
low speed mixture is described on page 9.
STEP 6: PRIME THE ENGINE
Connect the plug from the EZ-Start control box into the
connector mounted at the rear of the car. The plug is keyed so it
will only insert one way. Closely watch the fuel line going into the
carburetor. Hold your finger over the exhaust outlet and press the
button on the EZ-Start until the fuel moves through the fuel line
towards the carburetor. Once fuel reaches the carburetor, STOP.
If you press the EZ start button too long, you will flood the
engine and the EZ-Start will not be able spin it over (see page
13). With a full tank of fuel, it will only take a second to move the
fuel up to the carburetor.
STEP 7: SHUTTING OFF THE ENGINE
Before starting the engine it is important to know how to shut it
off. The correct method is to pinch and hold the carburetor’s fuel
line at idle speed, until the engine dies.
STEP 8: START THE ENGINE
Before starting your engine, review the safety and driving
precautions in this manual. (page 3 & page 7)
1)
Turn the radio system on (transmitter then receiver). Place the
car against a curb or some other immovable object to prevent it
from moving forward.
2)
Press the start button on the EZ-Start to turn over the engine.
Do not hold for more than 5-10 seconds to start the engine.
Once the engine has started, it may be necessary to continue
to hold the start button to keep the plug lit until the engine
has warmed up.
Note:
The red LED on the EZ-Start will light when the start but-
ton is pressed. This indicates that the glow plug is hot (ignit-
ed). If the LED does not light, make sure that the glow plug
connector (blue wire) is firmly attached to the glow plug. If the
connection is secure, and the LED still does not light, replace
the glow plug with a Traxxas, standard plug #3230.
3)
If the engine did not start in step 2, prime it again and retry.
Continue this sequence until the engine starts.
