SPARK PLUGS
The proper spark plug for the
Kolpin Powersports 180
is the NGK C7HSA or NGK CR7HSA. The spark
plug gap should be between .024 ~ .028 inch (0.6 ~ 0.7 mm). An incorrect spark plug gap can cause the
spark plug to foul.
The spark plug and its condition is an indicator of how the engine is operating. The firing end of the spark
plug should be checked after the engine has warmed up and the vehicle has been driven at higher speeds.
Immediately check the spark plug for correct color:
1.
Normal
– The insulator tip is gray, tan or light brown. There will be a 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 carburetor adjustments.
2.
Wet fouled
– The insulator tip is black. A damp oily film covers the firing end. There may be a
carbon layer over the entire nose. Generally, the electrodes are not worn. General causes are
excessive oil due to low compression or incorrect carburetor adjustments.
