what are the initial settings for the hi and lo speed screws on a two stroke mantis

1 comments:

The initial settings for the high and low-speed screws on a Mantis two-stroke tiller/cultivator are:

- The "RED" screw is for high-speed adjustment.
- The "WHITE" screw is for low-speed adjustment.

If the engine runs rough or hesitates, adjust the WHITE (low-speed) screw counter-clockwise one-eighth of a turn at a time until there is a smooth transition from idle to high speed. Repeat as needed. The axles should not turn at low idle when adjusted correctly.
