Do you guys know how to make an engine shut off. The only way I do it is take a vavle from a fish tank air lines and hook it in to my fuel lines and when I kill the engine I just turn the vavle. Is there any other way to do this .
 
I knew that

I know that. That is why I'm trying to find a differnt way to kill the engine
 
the only ways I know of to stop an engine is to pinch the fuel line or plug the tip of the exhaust. If you have a metal exhaust pipe you will prolly want to use a rag or your shoe to cover the exhaust because the metal pipe can get very hot.
 
They make little plastic things that are cone shaped that you stick into the pipe's stinger. A guy at the track has one and I think it's a fantastic little thing; no more burned fingers.

Plugging the exhaust is the fastest way to stop one of these motors - especially if the engine/linkage has a problem and the throttle is stuck open. Instant choke.
 
Pinch the fuel line.
When you do this, you cut off the fuel. Plugging the exhaust tip works, but stalls the engine by flooding it.
Pinching the line is the preferred method.
 
Pinching the line can have a few disadvantages. Usually you have to remove the body before gaining access to the fuel line. Pinching the fuel line completely is often very difficult, so you can end up letting some gas through and it forces the engine to run ultra lean for awhile; often times causing the engine to rev a high rpm's until it dies. Getting your fingers close enough to the carb to prevent most of this can be difficult to do without burning your hands on the surrounding engine and pipe.

If I am flooding my engine when I stall it with the exhaust plug, I'd never know it. The engine never has a hard time starting next time around, even if I start it again immediately.
 
I like pinching the fuel line. Plus its a quick bottom end tuning test.

BTW there is residue oil still in the case so running lean for 2 seconds is not going to hurt it.
 
well i had my first engine i was doing in the proper way with putting ur finger over the exhaust end but i could not be bothered with that any more so i started to pinch the fule line because the other one can hurt. and about a week later my engine packed up. i got another engine free as it was still under its warantie. so i did the fule line trick ( pinching it ) again and this time it lasted for 1 month. i thaugh that it must be pinching the fule line that makes it cease so my next engine i decided to do it the proper way and i have used that for 1/2 a year and still no problems.
Also if you reed the manual when you get the car it tells you to only pinch the fuel line in emergancies.
So i think i will still stick to putting a cloth over the exhaust end as this makes your engine last longer.

do not pinch the fuel line it will trash the engin

You are wrong on this one. Pinching the line is till the engine shuts down is also the test for how lean or rich your LSN is. If you trashed your engine, it was for other reasons.
 
if pinching the fuel line is so bad for the engine then why does the revo have a plastic pinch clip on the fuel line for shutting the engine down?I've been using the pinch method on my trucks and I haven't had any engine problems.

well hpi told me not to pich the fuel line because it trashed your engine so i don't know why the revo's do.
 
I've heard good and bad about both ways. "It creates a too-lean condition"... "It floods it"... I think the debate could go on forever.

If I had a choice I'll take the flood. Not to mention that one of those Dubro rubber exhaust tips on the stinger make it extremely simple to kill the engine. It also makes the engine easy to prime when it's completely devoid of fuel.

I guess my million-dollar idea would be to design a mechanical compression relief valve that could be incorporated into the cylinder head. Add a servo for the third channel you might not be using and your kill switch is then remote. I'll tell my design team to think carefully, mechanical valves at the cylinder head could snap or shear easily in a roll-over.
 
If you guys ho think it is a good to pinch the fuel line. Rip the fuel line of the carb becuse that is all you are doing starving the engine fuel and get redy to have a big hole in your wallets wher the cash use to be .
 
If you think it's so bad to pinch the fuel line to shut off your engines, then you should make sure you don't EVER run out of fuel while running.
It's the same thing as an empty tank. No fuel and it shuts down. Do you destroy your engine by running out of fuel? No. It's common.
When you're told not to leave fuel in the tank, but to run it dry, does THAT destroy your engine? No.
