The Ultimate Chain Saw Quiz
by Staff
You've just bought your first chain saw, and with good maintenance it may be the last time you'll need to buy one. But how does it work and what do you do with it? Take this quiz and learn how.

Where are the cutting teeth located on a chain saw?

  • on the chain
  • on the engine
  • on the pump

What horsepower does a regular 16-inch (40.6-cm) chain saw operate on?

  • 1.5 horsepower
  • 2 horsepower
  • 3 horsepower

How frequent are the rotations of a two-stroke engine?

  • as often as a four-stroke engine
  • twice as often as a four-stroke engine
  • half as often as a four-stroke engine

What is located under the cover plate of a chain saw?

  • the throttle trigger
  • the pull-cord handle
  • the centrifugal clutch

What is the purpose of the air intake openings?

  • to supply air to the spark arrestor and spark plug
  • to supply air to the engine and carburetor
  • to allow for the release of hot air

What is the name of the component that obstructs air flow?

  • the choke
  • the magneto
  • the pawl

What metal is the flywheel disc made of?

  • copper
  • steel
  • aluminum

When the engine is idle, what keeps the chain from moving?

  • the drum
  • the crankshaft
  • the centrifugal clutch

How is the centrifugal clutch different from the clutch pedal in a car?

  • It works automatically.
  • It is painted a different color.
  • It is much smaller.

What does the magneto do?

  • It attracts magnetic energy in order to keep the metal disc rotating.
  • It generates a surge of high voltage for each revolution of the crankshaft.
  • It measures the force of power needed for each revolution of the crankshaft.

How many coils are in the magneto?

  • one
  • two
  • three

What is the revolution ratio of the two coils?

  • The secondary coil turns 10 times more than the primary one.
  • The primary coil turns 100 times more than the secondary one.
  • The secondary coil turns 100 times more than the primary one.

Why does a chain saw need a carburetor?

  • to regulate the engine lubrication
  • to control the mix of fuel and air
  • to monitor engine overheating

Which of these is the best description for the carburetor?

  • It's a handle.
  • It's a tube.
  • It's a plate.

When the throttle plate is virtually closed, the engine is:

  • idling
  • operating on full power
  • overheated

What is bolted into the engine of a chain saw?

  • the venturi
  • the flywheel
  • all the other components

What lies at both ends of the crankshaft?

  • mufflers
  • roller bearings
  • pistons

Approximately how big is the piston?

  • 1.5 inches (38.1 mm) in diameter and 1.5 inches high
  • 3 inches (76 mm) in diameter and 3 inches high
  • 5 inches (127 mm) in diameter and 5 inches high

How much does an ordinary chain saw cost?

  • about $100
  • no less than $250
  • more than $500

The electrical generator (or magneto) creates electrical currents. What is their nature?

  • They're low-voltage spurts of electrical energy.
  • They're periodic high-voltage pulses.
  • They're continuous currents.
