KINROAD 150 SERVICE MANUAL
SPARK PLUG
a. Remove the spark plug and inspect it each time you change the
oil. (Use a spark plug wrench) The electrodes should be kept
clean and free of carbon. The presence of carbon or excess oil
will greatly deter proper engine performance. If possible, check
the spark plug gap (area between electrodes) using a wire feeler
gauge. This specification is 0.025"-0.030".
b. Before installing spark plug, thread lightly with graphite grease if
possible to ensure easy removal next time the spark plug needs
inspection.
c. It is advisable to replace the spark plug at least once a year to
insure easy starting and good engine performance.
FRONT WHEEL ALIGNMENT
1. The front wheels should be "toed-in" from 1/8" to 1/4"~ To check alignment measure distance from A to
B to the centerline (CL) of the tires with the wheels pointed straight ahead. For the proper toe-in
dimension A should be 1/8"-1/4" greater than dimension B.
2. Loosen the lock nuts on both sides of Front Tie Rods. To make Dimension B smaller, screw the rod left.
If B needs to be longer, screw the rod right. Tighten the jam nut tightly against the rod end. Recheck the
distance and repeat the above steps until the Dimensions are the same as data in paragraph 1.
