a probability that the piston, cylinder, or connecting
rod will be damaged.
How is a hydraulic lock Remove a spark plug from the locked cylinder and

It is an ignition system using a magneto with a brush-
type distributor and a coil that has no secondary
wiring. Low voltage is directed from the magneto to a
What is a low-tension transformer mounted on the cylinder head. Her the
ignition system? low voltage is boosted to a high voltage and is
directed through a very short high-tension lead to the
spark plug. There is one transformer for each spark
plug.
It is a cam ring that rides on a shelf-type bearing with
a large amount of clearance between the bearing and
the ring. When adjusting the valves on an engine with
What is a floating cam ring
a floating cam ring, the pressure of the valve springs
on a large radial engine?
on the opposite side of the engine must be removed
so the cam ring will be tight against the bearing for
the valves being adjusted.
Why is valve clearance Most horizontally opposed engines have hydraulic
adjusted on radial valve lifters that keep all of the clearance out of the
engines, but not on most valve train. Radial engines have solid lifters.
