I have a Troy Bilt trimmer model TB675EC...4 cycle engine. Problem that has arisen is that it dies at high speed and under load. Starts up and runs at idle well
Have replaced new carb, fuel lines, fuel filter, clean air filter, new plug, correct adjustment on valves, fresh fuel. Give it throttle and put it under load...runs rough and dies. Starts right back up at idle. Any thoughts?

Fuel starved, carb should have an idle adjustment which sounds like it is fine. Look for the second adjustment
