It also sucks any dirt that may be in your filter right into your engine..One of the first things I was taught was not to plug the stinger to stop my engine. I use the back of my tuning driver to stop the flywheel. It has that rubber stopper on the end which was made for...YUP!!! plugging the stinger, but it works great with stopping the flywheel also

I've plugged the exh for years my engines they last for many gals of fuel. I kick out it hurts the bearing like how are you going to hurt metal bearings Another thing plugged the exh stops the airflow through the engine. I don't have issues with restarting the engine fires right back up.

I'd say the best way would be to run it out of fuel...?
No harm done to the engine that way huh?

Well thanks for telling me that..
I am new to nitro...the owner of my LHS said no matter what, the best thing to do is always run the car totally out of fuel......

he is right in a way, cause any left over fuel will cause corrosion to the engine, it is better that u stop it and then drain any unburned fuel out from the engine the lube it with ARO...

Theres no correct way to stop nitro engine
Pinch fuel line makes engine run lean and engine dies. Hard on glow plug and engine
Plugging exh stinger
Jamming something into the flywheel which instant stops the engine. Moving parts come to sudden stop hard on rod and piston.
So where is no best way just your preferred way you want to.

I think there are 3 correct ways to stop an "idling" engine.
Pinch the fuel line. Why not, everything has a good coating of oil on it. If it races up to max RPM's when you do this you need to look at some other issues. Raving up 5,000 RPM's should not hurt anything.
Pressing finger against flywheel. Why not. You are not bringing it to an abrupt stop, there will be some slippage. If you can jab an object into the flywheel and there is absolutely no slippage, then some additional stress would be added, but its hard to do.
Covering up the stinger. Think I have already covered that. Go for it if that is what you want to do.
How you don't want to stop the engine is by pinching off the rubber boot under the air filter. Don't laugh, I've seen it done. May work for a short time but you will create a leak over time allowing dirt in.

The best way to stop a runaway is by pinching off the the rubber boot under the air filter...kills the engine instantly and keeps you out of harms way...

Well guys. Think about what happens.
Pinching fuel line, runs it lean but like ed said, it has oil why would that matter so much to run 3 secs on oil?
Plugging the stinger, it causes pressure to build on the rear bearing and damages it? Worst way i guess...
Stopping the flywheel, stretches the rod.
Well, lets think of some different engines. Normal piston ringed engines.
Lawn mower, most just close the carb fully.
Weed wacker, pinches the line.
1/1 car, kills the spark plugs.
Now what i gather is that the best way to do this would be to just get a glow plug wrench and loosen it to let the pressure go and let it die. What could that hurt? Only the threads MAYBE on the button because of going in and out so much but still.

I also think loosening the glo plug is probably the worst way to kill an engine. I thought about it, and you would be surprised to see how long your plug will still work as you keep loosening it. I have had a plug on my engine before that was in by maybe one or two threads and it was still running fine. And, anytime you uscrew it there is dirt in the threads and the pressure from the combustion chamber is bound to let some dirt in. It will actually suck air from around the plug. Very bad. you might as well rip the air filter off and plug it. It would do less damage.

I noticed some of you said when you stop the engine put the piston back on bottom dead center (BDC). What is the purpose in this and mainly, how can you tell when its on bottom center by feeling? What does it feel like?
like when I turn my motor over by hand, it feels like it gets tight, then with some force, it will rotate all the way around and feel "loose" rather. Would that be BDC?
