the engine is thus running without power. there
should be no jarring or knocking with each revo-

the hand on the head of the cylinder while the
engine is running and if there IS any disturbance

the most vital points pertaining to Its construction
and the advice of some reliable expert should be
taken on this matter before making a purchase
