When a piston has reached the top of its stroke, it is known as:

• IRS

• ABC

• BDE

• TDC

The connecting rod serves as the link between the:

• Crankshaft

• Crankshaft and cam journal

• Piston and crankshaft

• Camshaft and piston

When air passes through the carburetor venture:

• velocity and pressure increases

• velocity increases and pressure decreases

• velocity and pressure decreases

• velocity increases and pressure remains constant

Atmospheric pressure can vary slightly because of:

• altitude

• temperature

• both a and b

• none of the above

A general rule of thumb to follow is to allow a clearance between the cylinder and piston of ____ per cylinder diameter

Stroke is the total distance moved by the piston:
