The WilTec C178F may not start for several reasons:

1. Electric Start Issues – If the accumulator liquid level is too low, the electric motor may not receive enough current to operate.
2. Engine Run Time – If the motor has been used for too long, the accumulator voltage may drop, preventing the engine from starting.
3. Winter Conditions – In cold weather, the engine may be difficult to start. Adding 2 cc of machine oil after removing the rubber seal plug can help.
4. Key Switch Position – The key switch must be in the "ON" position while the engine is running.
5. Fuel Issues – If there is insufficient fuel or the fuel quality is poor, the engine may not start.
6. Oil Level – If the oil level is too low, the engine may fail to operate properly.

Checking these factors can help diagnose and resolve the starting issue.
