Hard-starting Rustler

Radio Control Car Action, Sep 2000 by Buono, Derek

I have trouble getting the engine started on my Traxxas Nitro Rustler. It seems to take a half hour before it finally fires. I have checked everything and can't seem to find a problem. [email] CHRIS TRAIL

Starting a vitro engine requires air, fuel and an ignition source. First, make sure the engine is not deprived of fresh air Check the air filter and make sure it is clean. Try to start the engine without the air filter. Then put on the filter while the engine is running, and if the idle speed changes drastically or the engine shuts off. the airflow is being restricted.

Next, check to make sure the engine is getting the fuel it needs. Pull the line feeding the carburetor and aim it at a piece of cloth (not near an open flame) in a well-ventilated area. Remove the line from the exhaust's pressure fitting, and gently blow into it. The fuel should freely flow out of the other end, feeding the Garb. If there is considerable resistance, check each part to see what is causing it. When the fuel flows freely, reconnect the line to the Garb and again gently blow into the pressure line. Be careful not to put too much pressure in the tank because fuel will come back up the pressure line once you stop blowing. You should be able to see fuel enter the Garb. Reconnect all lines and restart the engine. If everything is in check, but it still doesn't start, it is time to Check the ignition.

Remove the glow plug and hook it to the glow igniter. The plug's element should glow a bright white/orange within a second. if you are using an EZ-Start system, attach the plug to the wire, hold the plug to the side of the head, and turn the engine over. You should get the same results: if the plug doesn't glow brightly and the igniter/battery has been charged; change the plug.

When you have checked everything, reconnect all lines and wires and try to start the engine. it may take a few seconds for fuel to reach the Garb because all the fuel lines were disconnected. To speed this up, place your finger over the exhaust stinger to force fuel into the cart. Unless the engine adjustments are way off, it should fire right up.
