Troubleshooting - Honda GCV520 Owner's Manual

TROUBLESHOOTING

Engine will not start using recoil starter:
1. Are the battery cables securely connected and free of corrosion?
2. Is the battery fully charged?
3. Is the fuse good (if equipped)?
4. Is the engine switch in the ON position?
5. Is there enough oil in the engine?
6. Is the fuel valve ON (if fuel line is equipped with a valve)?
7. Is there fuel in the fuel tank?
8. Is gasoline reaching the carburetor?
To check, loosen the drain screw with the fuel valve ON.
If any fuel is spilled, make sure the area is dry before testing the
spark plug or starting the engine. Fuel vapor or spilled fuel may
ignite.
9. Is there a spark at the spark plugs?
a. Remove both spark plug caps. Clean any dirt from around the
base of the spark plugs, then remove both spark plugs.
b. Install the spark plugs in the spark plug caps, and ground the
side electrodes to any engine ground.
c. Turn the engine switch to the START position (with a recoil
starter not equipped), or turn the engine switch on and pull
the recoil starter (with a recoil starter equipped), and see if
there are sparks at the electrode gaps of both spark plugs.
d. If there are no sparks, replace the spark plugs. If OK, reinstall
the spark plugs. Try to start the engine again according to the
instructions.
10. If the engine still does not start, take the engine to an authorized
Honda dealer.
