Spark Plugs

Spark Plug Insp ectio n

Normal Plug

The normal insulator tip is gray, tan or light brown. There will be few

combustion deposits. The electrodes are not burned or eroded. This

indicates the proper type and heat range for the engine and the service.

NOTE: The tip should not be white. A white insulator tip indicates

overheating, caused by use of an improper spark plug or

incorrect carburetion adjustments.

Wet Fouled Plug

The wet fouled insulator tip is black. A damp oil film covers the firing

end. There may be a carbon layer over the entire nose. Generally, the

electrodes are not worn. General causes of fouling are excessive oil,

use of non-recommended injection oil, improper use of the choke, or

incorrect carburetion adjustments.

Recoil Housing

To prevent possible engine damage,

always drain the recoil housing (1)

afteroperatingtheATVinverywet

conditions. This should also be

done before storing the ATV.

Water will enter the recoil housing

if the starter handle is disengaged

from the rope guide when under

water.

The drain screw is located at the

bottom of the recoil housing. Use a

wrench to remove the screw. Be sure to reinstall the screw after

draining the housing.

NOTE: Do not open the crankcase drain unless the engine has

ingested water. On 4-cycle engines, some engine oil will be

lost if the crankcase drain is opened.
