ANY IDEA?

Use proper spark plugs: BR8ES

Check the spark plugs, make sure they are not fouled.

Use fresh fuel

Make sure the carburetor is clean and none of the passageways, airways or jets are plugged.

If it is overheating, make sure there is 2 stroke oil mixed with the fuel at 50:1( if not oil injected)

Check for cracked carburetor boot(will cause overheating)

If fan cooled, make sure belt is operational

Make sure the clutch springs (primary-engine and secondary) have been changed. Worn springs will make the engine bog with a lack of power

Make sure the drive belt is the proper size and is not worn. An improper sized or worn belt will also cause a lack of power and engine bog.
