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

  1. I have a 212cc, 6.5 Predator horizontal shaft engine. It is mounted to an old MIGHTY MAC compost shredder that probably had a 3-4 HP side valve engine on it. The Predatoer will start easily, often without the choke even when cold. It sits and runs fine BUT when I engage the belt drive to operate the shredder it will run OK only to shut off exactly as if it ran out of gas. Seems to happen quicker if engine is running faster. This occurs BEFORE I even get a chance to load any debris into it. Very few hours on it as each year it runs for shorter & shorter periods. Clean, gas, ethanol free, plug pretty clean considering how much time it was started on choke and didn’t have much chance to run & warm up fully. Good fat spark, air cleaner clean, no crud of any kind in the float bowl. At wit’s end. Ran Ok for a few hours the first year tho did exhibit this problem after it would run for 15-20 min back then.
    Thanks for any ideas.


  2. Last time I rode my hemi 212cc motor bike something could have broke or came lose in the motor it wouldn’t put out any power to the clutch and it made unpleasant sounds what should I do to fix my problem and what could it be???
