Small Engine #67-85

Flo jet carburetors must have the float adjusted or set __________ to operate properly.

• Level

• Vertical

• Horizontal

• Both A & C

A loss of spark when the engine reaches operating temperature generally indicates a:

• defective coil

• defective condenser

• ruptured diaphragm

• faulty air cleaner

What spark plug appearance clearly indicates the possibility of too 'lean' a carburetor fuel mixture for the 2 cycle engine?

• Dry or damp black soot on the insulator or shell

• Burned and badly eroded electrode

• Light tan or brown insulator

• Insulator has gray or white blistered appearance and a burned electrode

If you notice fuel dripping from the carburetor. The problem could be:

• The fuel line is clogged.

• The float is stuck in the closed position

• The float is stuck in the open position

• The fuel valve is in the on position

Which of the following describes the secondary winding of a magneto coil?

• Many turns of fine wire

• A few turns of fine wire

• A few turns of heavy wire

• Many turns of heavy wire

Which of the following spark plug tip insulator descriptions best indicates a 'hot' spark plug?

• Long

• Thin

• Thick

• Short

Which of the following is a part of the ignition coil?

• Air Gap

• Condenser

• Primary winding

• Breaker points

The ignition coil of a gas engine adjusts the secondary circuit current for the spark plugs by increasing the:

• Voltage

• Resistance

• Amperage

• Frequency

A sheared or partially sheared flywheel key would cause:

• Ignition timing to be off

• Valve timing to be off

• PTO shaft slippage

• An increase in voltage at the spark plug

The relatively low voltage produced in the primary coil windings is increased by the:

• Lead wire going to the spark plug

• Rapid spinning of the flywheel

• Induced voltage in the secondary circuit

• Action of the condenser
