hour on top gear when want to pick

hard. What 10 the eause7
The fact that your motor knocks
when tho spark is halfway advanced
when you are acceiera;ing from
speed of fifteen miles IN hour on high
gear does not indicate that there Is
anything wrong with Your motor Try
retardiue the spark further under these
conditions and see II the car does not
run all right. The idea to keep In mind
when using the spark lever is to set it
| at the point just below that ut which
| the motor will knock under the partic-
nlar conditions that the motor is OPP
Grating under at any given time

and three quarts of oil when up to the

ing does not seem to be caused by any
of these conditions it might be well to
reduce the level OF oil in the crank
case, but before taking such a step
you should confer with the manufac-

pair man.
