Something To Punch When Frustrated
Preparing Your Engine For Start Up:
Turn your engine over once by hand using the flywheel. You will come to a point where the engine is difficult to turn over. This is called the TOP DEAD CENTER (The point where the engine is compressing the air and fuel mix with the most pressure it can produce). A good idea for a first start up of and engine is to use a hair dryer to heat it up for 2 minutes and this will help make it easier to turn over and start. Mark an arrow with permanent marker where your Top Dead Center is on your flywheel. This will help you in determining your Bottom Dead Center. First make sure that your glow plug starter is fully charged and ready to be used, next take off your air filter. Turn on your radio and adjust the throttle trim/carb accordingly. The air intake should stay open at least 1mm when the car is at idle.
Starting Your Engine:
Pinch the pipe line(the fuel line going from your tank to you exhaust pipe). While plugging the exhaust turn the engine while watching the fuel line for any movement. You will see fuel move through the line and up to the carb. Once it reaches the carb turn the engine over once more. Now pull on the starter (if you are using a pull start, If not then use the starter as directed in the instruction manual) exposing only 75% of the string so you do not break the starter. NOTE: These movements need to be short and quick.
Once the engine starts stop pulling on the pull start and allow the plug warmer to camp on the glow plug for an extra 5 seconds. Give it some small amounts of throttle in order to keep the car alive (don’t panic if the car dies, just start it up again).
Breaking In The Engine:
Once it stays running you need to allow the car to “Free Idle” for one whole tank of gas. This means that you need to get rid of all forces working against the engine by placing the center of the car on an object that is above the ground allowing the wheels to spin freely (Hence the name “Free Idle”). Run it a little over idle and don’t allow the engine to heat up much. Try keeping it under 1/4 throttle. Run it like this for 2 more tanks of gas, allowing a ten-minute break in between the tanks. You will no need to position the piston at Bottom Dead Center after letting the engine cool all the way. Put a line on the opposite side of the mark on the flywheel. Go ahead and start it up again and now you should find that the engine starts up a lot easier. You can now start tuning the engine for optimum power and performance.
Tuning The Nitro Engine:
Start off by driving around at full throttle on some flat ground. Make sure you pay attention to the noise the engine is making and the smoke the exhaust pipe is producing If the engine sounds like it is making a screaming sound and the exhaust is only producing little or no smoke then the carb is set too lean and you need to turn the needle 1/8 turn toward open. If the engine is making a boggy sound and there is a thick trail of smoke then the carb is too rich and you need to turn the needle 1/8 of the way opposite of before.
