Default shutting down my nitro engine

I was at the track today with my RC10GT RTR+ and was having a very difficult time killing the motor. All the other nitro truck guys plug the exhaust for less than half a second and their enignes quite...I plug mine for 15 seconds and its still running. The motor is the AE .15, any ideas on how to fix the problem? or what the problem is for that matter.

First of all, don't do what those guys are doing, THAT IS BAD!!! Try pinching the supply line to the carb.

As for the problem, maybe you have an exhaust leak? Hell I don't know, I've never had that happen before.......

pinch the fuel line to the engine and it should shut off just fine

runnin rc10 - 15 seconds? That's a sign of a big exhaust leak. Check your coupler and pressure line.

Pinching the fuel line to the carb is one of the WORST ways to shut off an engine. Starving the engine for fuel and lubrication in order to shut it off will lead to wear and burn out glowplugs.

The best way to shut down an engine is to hit the flywheel with your shoe (wooden clothespins also work well). Make sure you're very careful, and don't use your hand!

How are you careful when you try and kick the flywheel? i dunno, but i'd be pretty scared to try that, any other suggestions besides pinching the fuel line? that has worked for me so far, or to simply just run it completely until there is no fuel left for it to run..

Just turn it over and press on the flywheel.

I use my finger. I thought it would rip my finger off, but it doesn't.

I still have 4 on 1 hand.

It stops really easily.

Dubro makes a flywheel tool for shutting off your nitro engines. I use my finger but some people are scared to try it. If your flywheel isn't all burred up and fairly smooth their is nothing to hurt you.

i pull the air filer off and put my thumb over the carb doesnt starve for fuel so lube still goes in engine but shuts off almost immediatly with no air going to it

Brandon - That's the only method that is as close to being as harmful to your engine as pinching the fuel line!

You should never remove the only means of keeping the inside of your engine clean unless you're in a clean environment.

It will if the engine isn't at idle. Safest bet is the shoe or other un-bodily object.

the only reason I didnt run the tank until empty is becuase I was having problems with a ball cup and kept losing my dog bone before the tank was empty. And from there we couldnt hardly get the truck to shut down. So if it is a leak, how do I go about fixing it? Replace the pressure line? thanks for your help

I agree... it really doesnt hurt if you use your finger on the flywheel... as long as your nail is facing in the direction of the way its spinning...

I used a clothespin for a long time before i sold my nitro...
