  If your Power Fist Outdoor Cart isn't moving while the engine is running, it could be due to the gear not being properly selected or the clutch failing to engage. First, make sure the gear lever is correctly positioned and not in-between two gears. If that's not the issue, consult the 'Adjusting The Clutch' section in Care & Maintenance to resolve clutch engagement problems.
