RE: brushcutter engines

Typically, these engines are converted using the flywheel end as the output shaft as most flywheel ends of trimmers/brushcutters turn counterclockwise.

The threads on the flywheel end of the crankshaft is usually 8mm

You need a carb with both a high speed and a low speed mixture adjustment. Often a larger carb is used from what was on the original engine.

The mixture adjustment is for the prop load on the engine and not for altitude adjustment as these carbs all have altitude compensators.

Blower engines often turn the opposite direction so they have to be reversed or use the opposite end of the engine in some cases.
