TROUBLESHOOTING

Engine

If

Check

 

 

 

 

Poor Engine Performance

Fuel:

 

• Dirt in fuel system or fuel is old.

 

Replace fuel with fresh stabilized fuel.

 

Obtain fuel from another supplier

 

before suspecting machine problems.

 

Suppliers blend fuels differently and

 

changing suppliers will generally solve

 

any performance problems.

 

• Fuel blended with alcohol or ether

 

may contribute to performance

 

problems by causing gum and varnish

 

deposits, especially if fuel is stored for

 

several weeks or more. Obtain fresh

 

fuel.

 

 

Engine Will Not Start Or Is

• Park brake lever not in the proper

Hard To Start

position.

 

• OPC switch not depressed. Stand on

 

platform or adjust switch.

 

• Check that motion control levers are in

 

neutral and neutral switches are

 

correctly adjusted.

 

• PTO engaged.

 

• Stale or improper fuel/fuel level.

 

• Plugged fuel filter.

 

• Plugged air intake filter.

 

• Spark plug wires loose or

 

disconnected.

 

• Spark plugs not gapped correctly.

 

• Blown fuse.

 

• Electrical problem – dead battery.

 

• Choke adjusted incorrectly. See your

 

authorized dealer.

 

 

Engine Will Not Slow Idle

• Carburetion problems. See your

 

authorized dealer.

 

• Bent or kinked throttle cable.

 

• Bent governor control.

 

• Incorrect governor idle control.

 

 

Engine Runs Rough or Stalls

• Plugged fuel filter.

 

• Plugged air intake system.

 

Fuel cap vent dirty.

 

• Stale or improper fuel/fuel level.

 

• Spark plugs not gapped correctly.

 

• Replace spark plugs.

 

• Choke adjusted incorrectly. See your

 

authorized dealer.

 

 

If

Check

 

 

 

 

Engine Knocks

• Engine oil level low.

 

• Reduce load. (Slower ground speed.)

 

• Fuel is bad. Fill tank with fresh fuel,

 

correct octane.

 

• Idle speed too slow.

 

 

Engine Overheats

• Clean cooling fins.

 

• Low oil level.

 

• Do not operate at slow idle. Operate

 

at fast idle.

 

• Cooling air intake screen is dirty.

 

• Plugged carburetor air intake filter.

 

• Plugged air intake filter.

 

• Operating at too fast ground speed for

 

conditions.

 

 

Engine Lacks Power

• Reduce load.

 

• Plugged air intake system.

 

• Plugged fuel filter.

 

• Improper type of fuel. Drain tank and

 

fill with correct fuel.

 

• Clean cooling fins to help prevent

 

overheating.

 

• Replace spark plugs.

 

 

Engine Uses Too Much Oil

• Find and correct oil leaks.

 

• Incorrect engine oil.

 

• Plugged oil filter.

 

• Plugged air intake filter.

 

• Worn engine components.

 

 

Engine Backfires Through

• Throttle lever should be at low idle for

Muffler

thirty seconds before turning off

 

machine.

 

 

High Fuel Consumption

• Improper type of fuel.

 

• Plugged air intake system.

 

• Operating at too fast ground speed for

 

conditions.

 

• Improper valve clearance. See your

 

authorized dealer.

 

• Restricted air intake system.

 

 

Other Symptoms

• See engine manufacturer’s owner’s

 

manual provided with your machine for

 

additional information.
