Hi i just have a new monster truck and i have a problem with it: when i push the button for a while, my motor is turning off. Could you explane me the reason of it????

what button, what truck, what motor, electric or gas, who makes it, pictures, there are quite a few more pieces of info you need to provide for us.

ok so its a monster truck by nanda, 27cc, gas , and it makes me when i push the button on the controler for accelerate.

makes you what?...

I believe he is trying to say that when he tries to accelerate, it stalls out. The motor is running either lean or rich. I know there are better tuning sites but this is the first one that popped up on google.

Pay attention to the lean and rich symptoms about half way down the page. You need to determine which needle needs tuning and richen or lean in small steps so you don't over-do it.

makes him dance like a re incarnated MJ.........
