Youre needle valve could be set to rich, get someone to set reset it again. You can use a tachometer to make sure you get the perfect setting. Always set it slightly rich.

Generally, if an engine stalls when you advance the throttle, the problem is that the low speed mixture is too rich.

To test this, with the motor idling, pinch the fuel supply line. If the motor speeds up and then dies, lean out the low speed needle or open up the airbleed screw.

It really would help to know the make and model of the engine.
