Troubleshooting - Honda HS624 Owner's Manual

TROUBLESHOOTING
When the engine will not start:
1. Is there enough fuel?
2. Is the fuel valve on?
3. Is gasoline reaching the carburetor?
To check, loosen the drain screw with the fuel valve on. Fuel should flow
freely.
4. Is the throttle in the correct position?
Gasoline is extremely flammable, and gasoline vapor can explode.
If any fuel is spilled, make sure the area is dry before testing the spark
plug or starting the engine. Spilled fuel or fuel vapor may ignite.
5. Is the engine switch on?
6. 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.
d. Ground the side electrode at any engine gronud and crank the engine
to see if sparks jump across the gap.
l
Never hold the spark plug lead with wet hands while performing this
test.
l
Make sure that no fuel has been spilled on the engine and that the plug
is not wet with fuel.
l
To avoid fire hazards, do not allow sparks near the plug hole.
e. If there are no sparks, replace the plug.
If sparks occur, try to start the engine according to the instructions.
7. If the engine still does not start, take the snowblower to an authorized
Honda dealer.
If the auger or blower does not operate, check the shear bolts (p. 41 1.
Replacement shear bolts and nuts were supplied with your snowblower.
Additional shear bolts and nuts are available from authorized Honda
snowblower dealers. Do not replace shear bolts with ordinary hardware
bolts.
