Troubleshooting - Honda UMC425 Owner's Manual

When the engine will not start:
1.Is the engine switch in the ON position?
2.Is there fuel in the fuel tank (see page 21)?
Gasoline is extremely flammable and explosive under certain
conditions. Do not smoke or allow flames or sparks in the area.
3.Is gasoline reaching the carburetor?
To check, press the priming pump several times (see page 35).
4.Is the spark plug in good condition?
Clean, readjust gap and dry the spark plug. Replace it if necessary
(see page 47).
5.If the engine still does not start, take the power head to an authorized
Honda dealer.
