Troubleshooting - Honda GX31 Owner's Manual

TROUBLESHOOTING

When the engine will not start:
1. Is the engine switch in the ON position (on the equipment side)?
2. Is there fuel in the fuel tank?
3. Is gasoline reaching the carburetor?
To check, press the priming pump several times.
4. Is there a spark at the spark plug?
a. Remove the spark plug cap. Clean any dirt from around the
spark plug base, then remove the spark plug.
b. Install the spark plug in the plug cap.
c. Turn the engine switch ON (on the equipment side).
d. Grounding the side electrode to the cooling fin below the
spark plug hole, pull the recoil starter to see if sparks jump
across the gap.
e. If there is no spark, replace the plug.
If OK, reinstall the spark plug and try to start the engine again
according to the instructions.
5. If the engine still does not start, take the engine to an authorized
Honda dealer.
