Honda HR214 lawnmowers will break down if they are not taken care of. They require proper maintenance, which includes replacing the oil, spark plugs and air cleaner every spring. The hardest problems to diagnose are the engine problems because there are so many parts and pieces on it, including a spark plug that requires a specially-designed wrench to remove it. If you need any parts, read the owner's manual to find the correct pieces.

  1. 1

    Check a few different areas inside the engine if you cannot start the lawnmower. Open the fuel tank and make sure that there is gas inside. If there is fuel, check the spark plug, which is located on the front of the engine under a black hose. Pull the hose off with your hands and unscrew the plug with an adjustable wrench. Place a new plug into the hole and tighten it with the wrench. Slide the hose over the new plug. If the plug is fine, check the battery terminal and make sure that it is connected properly because any wires that are loose or not connected will prevent the engine from starting.

  2. 2

    Inspect the air cleaner, oil level and spark plug gap if the engine is overheating. Pull the air cleaner off the top of the mower and check for any dirt. If there is, it will cause the motor to overheat because it is getting chocked by dirty air. Try cleaning it out by blowing compressed air through the paper cartridge. Check the oil level by unscrewing the cap and pulling out the dip stick. If the level is low, the engine is not being lubricated enough, causing it to overheat. Fill the oil tank until the dipstick reads that it is full. Unscrew the spark plug with a spark plug wrench. Use a feeler gauge to measure the plug's gap. If it is not between 0.7 and 0.8mm, then adjust it until it is because a narrower or wider plug causes the engine to get too hot of a spark, which causes overheating.

  3. 3

    Inspect the blade if the mower is excessively vibrating. Make sure the blade is tightly secure onto the arbor because if it is not, it will cause a lot of vibration at full speed. Also, check it for any irregular bends as they will cause excessive vibration as well.

Tips and warnings

  • Allow the lawnmower to cool down for one hour before touching any part of the engine.
  • According to the Honda HR214 manual, put 10W-40 motor oil into the mower for general purposes.
