  Several factors could prevent your Coleman Engine from starting. The fuel tank might be empty or the fuel could be contaminated or stale; in these cases, fill the tank with clean, fresh fuel. The fuel filter might be clogged, requiring cleaning or replacement. The spark plug(s) could be fouled or of the incorrect type, so inspect, clean, or replace them. Also, check if the spark plug cap(s) are fitted incorrectly and refit them if needed. Damaged or poorly connected ignition wiring can also be the issue; check for wear or breaks, tighten loose connections, and replace worn or broken wires. Ensure the engine stop switch lanyard is attached.

  If your Coleman Engine idles irregularly or stalls, several factors could be the cause. Begin by inspecting the spark plug(s) and cleaning or replacing them if they are fouled or of the incorrect type. Check for any obstructions in the fuel system, such as pinched or kinked fuel lines. Ensure that you are using clean, fresh fuel and that the fuel filter is not clogged; clean or replace it if necessary. Inspect and adjust the spark plug gap as specified. Check the ignition wiring for any damage or poor connections, and repair as needed. Verify that you are using the specified engine oil. Also, ensure the air vent screw on the fuel tank is open, the fuel joint connection is correct, the choke knob is not pulled out, and the motor angle is at the normal operating position.
