Why MTD 808H engine fails to start?

  robertsonmeghanAug 13, 2025
  If your MTD Lawn Mower engine won't start, several factors could be at play. First, make sure the PTO knob/lever is disengaged (OFF). Next, ensure the parking brake is engaged. Check that the spark plug wire(s) are connected to the spark plug. Also, verify the throttle control lever is in the FAST position. If these steps don't work, pull out the CHOKE control (if equipped) and fill the tank with clean, fresh gas (less than 30 days old). Finally, check for a blocked fuel line, a faulty spark plug, or a flooded engine. Clean the fuel line or replace the fuel filter if needed. For a flooded engine, crank it with the throttle in the FAST position.

Why MTD 808H engine runs erratic?

  Jessica PerezAug 17, 2025
  If your MTD Lawn Mower engine runs erratically, there are several things to check. First, if the CHOKE is applied, push the CHOKE control in (if equipped). Next, make sure the spark plug wire(s) are securely connected and tightened. Also, check for a blocked fuel line or stale fuel; clean the fuel line and fill the tank with fresh gasoline (less than 30 days old). A plugged vent in the gas cap could also be the issue; clear the vent or replace the cap if damaged. Finally, check for water or dirt in the fuel system; drain the fuel tank and refill with clean, fresh gasoline. Replacing the air filter might also solve this problem.

  If your MTD Lawn Mower idles poorly, replace the spark plug(s) and set the plug(s) gap to .030”, because the spark plug(s) might be fouled, faulty, or have a gap that is too wide. Replacing the air filter might also solve this problem.

  To resolve excessive vibration in your MTD Lawn Mower, first, tighten the blade and spindle, and balance the blade, because the cutting blade might be loose or unbalanced. If the cutting blade is damaged or bent, replace it.

Why MTD 808H Lawn Mower will not mulch grass?
- B
  Beth SmithSep 1, 2025
  If your MTD Lawn Mower is not mulching grass effectively, make sure the throttle is in the FAST (rabbit) position, because the engine speed might be too low. Also, avoid mowing when the grass is wet; wait until it's dry. If the grass is excessively high, mow once at a high cutting height, then mow again at the desired height, or make a narrower cutting swath. Finally, check the blade; if it's dull, sharpen or replace it.

  If your MTD Lawn Mower engine overheats, check the engine oil level and fill the crankcase with the proper capacity and weight of oil. Also, clean any grass clippings and debris from around the engine’s cooling fins and blower housing to ensure proper air flow.
