Need help?
Do you have a question about the C302 and is the answer not in the manual?
Questions and answers
My C302 won't start
The Shindaiwa C302 may not start due to several possible reasons:
1. Fuel Issues: Old or separated fuel can prevent starting. Use fresh, clean two-stroke fuel and shake the fuel container before use.
2. Improper Starting Procedure: Ensure the stop switch is moved away from the STOP position, the choke is set to COLD START, and the purge bulb is pumped until fuel flows freely, followed by four to five additional pumps.
3. Engine Maintenance: Clogged air intakes, dirty cylinder fins, or blocked cooling passages can cause overheating or engine seizure. Clean the cooling system as part of regular maintenance.
4. Spark Plug Issues: A fouled or improperly installed spark plug can prevent ignition. Check, clean, or replace the spark plug as needed.
5. Fuel Left in Carburetor: If fuel remains in the carburetor for extended periods, it may prevent starting. Drain the fuel and follow storage procedures if the unit has not been used recently.
6. Improper Piston Position: Ensure the piston is at the top of its travel when reinstalling the spark plug after maintenance.
Addressing these issues should help the engine start properly.
