TroubleShooting Your .46

Recommended equipment for your .46: • Glo-Plugs: O.S. No.8, A5 or McCoy MC-9 • Fuel: 20% Traxxas, HPI 20 or 30%, O'Donnell 20 or 30%, Mugen 20 or 30%, Byron 20 or 30%. 20 or 30% fuels can be used but 30% fuels usually require richer fuel mixtures to compensate for the added nitro percentage! • Temperature Gauge: Preferably a handheld or Gun style; this device is the best way to prevent high temperatures which can damage your engine or drastically reduce its overall life. • Gloves: Due to this motors high compression when pulling the pull-start it is recommended to wear a glove to prevent injury to user. Carburetor Settings Adjust needles in this order. Note: All settings vary with climate and elevation. High Speed Needle: Between 3 1/4 and 3 1/2 Low Speed Needle: Turn Counter Clockwise OUT until FLUSH with the Slide ball- linkage and then Turn Clockwise 1 turn IN for stock setting. Mid-Range Needle: Turn Clockwise until needle stops then turn OUT Counter Clockwise 3 1/2 turns. (note: With carburetor slide held open. Turn midrange needle clockwiseto close, when you feel it snug, stop immediately. That is the closed position.) Starting Your Truckzilla with the Jump-Start Although the jump-start method is the more user friendly way to start the Truckzilla it cannot be used until the motor has been properly broken in. (Minimum 8-10 tanks) Even once the engine has broken in, some caution is needed to insure the life of the jump-start. Before you even attempt to start your Truckzilla you need to first check your glo-plug to ensure it is glowing bright, check the head bolts and tighten if necessary, also check to make sure you have proper throttle movement ( pulling trigger is OPEN pushing trigger forward is CLOSED, NEUTRAL the throttle is barely open.) Once these above things have been checked it is now time to fill the tank; now insert starter shaft into jump-start backplate. With your finger over the muffler hole hold the jump-start button down (or pull the pull-starter a few times) just long enough to bring the fuel all the way through the fuel line to the carburetor priming the engine. Now apply the glo- igniter to the engine; with a firm grip on the vehicle hold the button down. If the motor doesn't at least pop a few times or try and turn over after 10 seconds of continuous jump-start use disengage use and check the above items again. DO NOT hold the button down for more than 10-15 continuously or damage may occur. DO NOT use a power drill of any kind in place of the jump-start handheld unit or damage will likely occur. Starting Your Truckzilla with the Pull Start Starting your Truckzilla WILL be difficult at first due to the high compression. First make sure you are using the pull-start and NOT the jump-start provided with the kit as using the jump-start before break-in is complete will most likely result in damage to it. Next check over vehicle as stated in Starting your Truckzilla with the Jump-Start, now fill the tank with 20% fuel, and apply the glo-plug igniter to glo-plug. Now with a FIRM grip on the chassis using the opposite hand that you pull-start with or a friend holding the vehicle, pull the pull-start NO MORE than 12-14 inches out in rapid succession. Note: To make pull starting easier loosen glo-plug as needed to vent compression until started; once engine fires tighten glo-plug immediately!

Running Your Truckzilla Until around 10-12 tanks have been run through this engine it may seem very un-reliable; cutting out a lot or bogging excessively. To help avoid these problems during usage warm up the engine to running temperature before normal usage takes place. Now that you have reached running temperature and a smooth idle is maintained pick the vehicle up off the ground and slowly throttle up until throttle is open all the way. DO NOT hold at full throttle for more than a few seconds as this might damage the engine! Doing this will clear out excess exhaust residue from the exhaust system yielding If you notice a ruff transition from idle to full throttle or the engine bogging near or at full throttle; needle adjustments may be necessary.Temperature Range Through the course of the Truckzilla project HotBodies has observed and or heard accounts of running temperatures as low as 200 F and as high as 300 F. However we recommend that you try to keep your motor between 230-280 F. This is running temperature; Running temperature is best observed after the vehicle has warmed up and you have made a few passes at or near full throttle.

Miscellaneous Information DO NOT use a hardened steel spur gear as this will wear the clutch bell down in a matter of a few tanks of fuel. If you blow out a glo-plug and the filament in the glo-plug is missing inspect the internal works of the motor to insure that the filament is not somewhere inside the motor, which could cause severe damage to the motor if ran.
