The engine will often run fine at idle, but will die when it is throttled up. This is because there is less air moving through the engine at idle. When the engine is run at full throttle, especially under load, the air flow is much greater, which causes more back pressure, and results in the engine stalling.
When I open the throttle the engine dies?

Why does my trimmer dies when I give it gas?
One reason why one of these trimmers may die at full throttle is that too much oil is in the gas, which causes poor combustion.
