The briggs Fource is out of production - probably due to poor sales. The engine starts easily - probably better than the two cycle trimmers. The engine runs at 7000 rpm and power is good. Oil does not need to be added to the fuel.

On the negative side, the engine does not have the durability of the quality two cycle trimmers. The oil capacity is only 3 ounces and most owners do not monitor. Most owners yank the starter rope and the starter drive engages a plastic gear that strips easily. Overall, the engine is bulky and heavy.

My opinion is the Fource is no better quality than the cheap trimmers in Lowes and Home Depot.
