Taking Care Of Unexpected Problems; Engine Will Not Start - Honda BF5A Owner's Manual

TAKING CARE OF UNEXPECTED PROBLEMS
ENGINE WILL NOT START
1. Is the emergency stop switch clip in place?
2. Is the gearshift lever in neutral?
3. Is there fuel in the fuel tank?
4. Is the fuel cap vent knob turned to open?
5. Is the fuel system primed by squeezing the primer bulb?
6. Is fuel reaching the carburetor?
Loosen the carburetor drain screw to see if there is fuel in the carburetor float
bowl.
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.
7. Are the spark plugs firing?
a. Remove and inspect the spark plugs. Clean and dry the plugs, and
check the electrode gaps (p. 51).
b. Install the spark plugs in their caps, and ground the side electrode to any
engine ground away from the spark plug holes.
c. Pull the recoil starter briskly, and see if the plug sparks.
d. If the spark plugs are OK, reinstall them, and try to start the engine.
Engine overheats:
1. Is the water intake screen clogged?
2. Is the thermostat faulty?
