If your PTM Engines Engine won't start, several factors could be the reason. First, check if the battery is discharged and recharge it if needed. Ensure the fuel valve is in the ON position and the choke lever is CLOSED, unless the engine is warm. Also, verify that the engine switch is set to ON and that there is enough fuel in the tank. If the fuel is bad, drain the tank and carburetor, then refuel with fresh gasoline. Inspect the spark plugs for faults, fouling, or incorrect gapping; gap or replace them as necessary. If the spark plugs are wet with fuel, dry and reinstall them, then start the engine with the throttle lever in the FAST position. If none of these steps work, you may need to replace or repair faulty components.
