Alright for some reason my car keeps stalling. I am on my 6 tank of gas and it stalls after like 40 seconds. it just did this like 3 times. the engine slows down a lot and then it stalls. Can someone tell me whats wrong?[:@]

well are you letting it idle for 40 seconds? it sounds like your idle is just too low. 40 seconds though is a long time to let it idle, you can expect it to stall if the idle is set fairly low, or its slightly lean.

Or even slightly rich if its loading up on fuel in the engine, it just cools the glow plug too much. What kind of engine?

It is a stock rc10gt rtr, and i am not letting it idle, i will start it up and rev it up and start running it. Then it dies on me in less than 2 minutes. I tried turning up the idle speed but then i just have to turn it down when it warms up

when does it stall? when you apply the brakes or full throttle?

when i apply the throttle.

Sounds way lean to me... back out on the high speed needle and try it again.
Careful running it this way for too long without fixing it.
A bud just breezed through a brand new engine in less than two weeks like this.

so it is cutting out? sounds like its too lean. i suggest turning the needles back to stock adjustments and starting over from there.

alright but just the high speed needle right. i will tell you how it goes tommorow.

To start with, yes... if you find that you've opened the high speed needle out more than 2
or 2 1/2 turns, and it's still doing it... I'd screw the low speed needle out about 1/8 turn,
and start over. It could also be some air leak, or that you've roasted the piston/sleeve,
but we'll keep our fingers crossed for you By friend's started doing the same thing,
after running it without tank pressure (broken cap) and getting it extremely lean.
Now, it runs fine for a few minutes, but quits when it's warmed up.
