This may help out some people that are new to the world of RC and Nitro engines.
There are a few ways to shut off your engine.
1: Stop the fly wheel.
2: Pinch the fuel line.
3: Plug the exhaust stinger.
I think one of the best ways to shut down your engine was explained to me the other night and I thought I would share it with you.
Before anything you want to make sure that your throttle is in neutral.
Pull the fuel line off the carb. This will stop any fuel to the engine.
At the same time you want to plug your exhaust stinger. All your doing with the stinger is feathering it so the revs stay nice and low, you don't want to kill the engine with the pipe, just limit the revs so it doesn't scream as it leans out
The reason for this is that you are trying to burn the remaining fuel in your engine ONLY. As the engine revs high even for a couple of seconds you are heating up the combustion chamber even more and that starts to burn off the lubricants that will help keep your parts lubed for the next start up.
Why do we burn all fuel left in the engine? Nitro fuel retains moisture and as the fuel starts to evaporate it will release that moisture into your engine and cause it to rust over time.
You can drain whatever fuel that is left over in your feed line back into your tank. It should be ok for a couple of days but don't leave it to long or the moisture will start to break down your fuel.
On a side note, if you do not want to leave fuel in your tank put it into another fuel bottle. Do not put it back with new fuel because you might contaminate it.
Just to be sure that no fuel will enter your engine through gravity feed you can cap both the fuel line and the carb intake.
This method should ensure that with proper engine maintenance you will get maximum life out of your engine.
One more thing to add. When you do stop your engine for the day make sure you put the piston at BDC. This is especially important with newer engines. Putting the piston at BDC will keep the pinch between the piston and the piston sleeve when the engine cools. You want to keep the pinch as tight as possible as it will keep you engine compression as high as possible for as long as possible, that is until normal wear and tear take over.
