Predator 212cc Engine Troubleshooting

Predator 212cc Engine Troubleshooting

Some of the troubleshooting steps you should know about a predator 212cc engine are given below:

Main Problem: First problem we are about to discuss is “Engine is refusing to start”

Solution: This can be caused for three complexities.

  1. Fuel Related
  2. Ignition (Spark) Related
  3. Compression Related

Let’s take one by one, figure out the cause and what should be done:

Fuel Related Problems and Their Solution:

  • Cause: The fuel tank might be empty. Or the fuel valve is closed.
  • Solution: Fuel tank should be filled and open the fuel valve.
  • Cause: Gasoline is old or deteriorated. In a word, the gasoline is of poor quality.
  • Solution: You should drain the remaining and use fresh gasoline.
  • Cause: Gasoline might contain over 10% ethanol.
  • Solution: Check first whether this is the issue. If yes, use gasoline containing less than 10% ethanol.
  • Cause: Engine might be cold and the choke is not in its preferred position
  • Solution: Place the choke to its preferred position.
  • Cause: Dirty fuel passageways.
  • Solution: You should clean the dirty fuel passageways properly. To do so, use fuel additive. In the case of there having a heavy deposit, remove the deposit properly with care.
  • Cause: The carburetor needle is stuck
  • Solution: Take a screwdriver, press the carburetor float chamber very gently with the handle of the screwdriver.
  • Cause: The carburetor is not primed
  • Solution: You should pull the starter handle to prime.
  • Cause: Overage of fuel in chamber
  • Solution: Turn the choke to run position. Now you have to make the air out from the chamber. To do so, pull the start handle many times after removing the spark plug. Then reinstall the spark plug and move the choke back to its position.
  • Cause: Blockage of fuel filter
  • Solution: Your fuel filter is gone, change it.

Ignition (Spark) Related Problems and Their Solution:

  • Cause: The spark plug cap might be broken
  • Solution: Check the issue, if it’s broken then change the broken spark plug cap.
  • Cause: The circuit breaker might be tripped
  • Solution: Check the issue, if it tripped then reset the spark plug.
  • Cause: The connectivity of the spark plug might be poor
  • Solution: Check first whether this is the issue. If yes, properly connect the spark plug cap.
  • Cause: The spark plug might be dirty or wet
  • Solution: Clean the spark plug
  • Cause: Incorrect spark plug gap
  • Solution: Correct the spark plug gap. Take assistance from an expert if you do not know what to do.

Compression Related Problems and Their Solution:

Cause: The tappets or the engine valves are misadjusted

Solution: Contact an experienced technician and diagnose the ignition system. Repair them according to the problem.

  • Cause: The cylinder head might be damaged or loose
  • Solution: Tighten the head first. If the problem persists, replace the head gasket.
  • Cause: Broken or loose spark plug
  • Solution: Tighten the spark plug and replace if the problem continues
  • Cause: The cylinder is not properly lubricated
  • Solution: Apply lubricant into the spark plug hole

Main Problem: Engine Misfires

  • Cause: Loose spark plug cap
  • Solution: Check wire connections.
  • Cause: Damaged or incorrect spark plug
  • Cause: Low quality or old gasoline
  • Solution: Use quality gasoline that contains less than 10% ethanol.
  • Cause: Compression not correct
  • Solution: Diagnosing and repairing compression
  • Cause: Spark plug gap is defective
  • Solution: Replace the spark plug gap

Main Problem: Sudden stopping of engine

  • Cause: Low oil shutdown
  • Solution: Engine oil should be at a proper level. Always check the engine before every use.
  • Cause: Faulty magneto
  • Solution: Servicing of magneto by experienced technicians
  • Cause: Empty fuel tank or full of low quality gasoline
  • Solution: Use gasoline that doesn’t contain more than 10% ethanol
  • Cause: Improper fuel flow due to defective fuel tank cap
  • Solution: The fuel tank cap should be tested. If it continues, should be replaced
  • Cause: Poor connectivity of spark plug cap
  • Solution: Properly connect spark plug cap

Main Problem: Stopping of engine when under heavy load

  • Cause: The engine runs cold
  • Solution: Permit warming up of the engine
  • Cause: Unclean air filter
  • Solution: Clean or change element

Main Problem: Knocking of Engine

  • Cause: Overloading of engine
  • Solution: Avoid exceeding the load rating of the equipment
  • Cause: Mechanical problems such as spark timing not being correct, worn engine, and building up of deposit

Solution: Engine should be diagnosed and serviced by qualified technicians

  • Cause: Gasoline is old or of poor quality
  • Solution: Use 87+ octane fresh gasoline that is unleaded. Use gasoline that doesn’t contain over 10% ethanol (E15, E20, E85, and others)

Main Problem: Backfiring of Engine

  • Cause: Faulty magneto
  • Solution: Diagnosing and servicing of engine by experienced technicians
  • Cause: Gasoline is dirty or has low quality
  • Solution: Fill your fuel tank with fresh unleaded gasoline. The gasoline should not contain more than 10% ethanol
  • Cause: Timing is not correct
  • Solution: Check and correct engine timing
  • Cause: Engine is very cold
  • Solution: Prevent backfiring by using oil additives and cold weather fuel

Set Up Precautions

Some of the predator 212cc engine set up precautions are:

  • Better fuel storage should be used. Never keep your fuel or flammable materials close. Fume and gasoline fuel flammable and prone to explosion.
  • There should be many good fire extinguishers placed to easy to reach places.
  • Having a spark arrestor is necessary as engine operation may birth sparks. If not arrested on time, may cause a fire in dry vegetation. The operator should communicate with local fire agencies. This will provide fire prevention requirements.
  • You should use your predator 212cc engine on a flat surface after set up. The surface should also be well-ventilated.
  • Make sure you wearing safety goggles approved by ANSI. You should also wear your respirator or dust mask and work glove during set up.
  • Use gasoline that doesn’t contain over 10% ethanol.

Operating precautions

The operating precautions of using predator 212cc engine include:

  • You can die in a few minutes when you use predator 212cc engine indoors. The engine exhaust is made up of a poisonous gas called carbon monoxide. You can’t see or smell the gas.
  • Avoid using the engine in your garage or home. This is included when your doors and windows are wide open.
