How to fix a McCulloch M17538H that will not start?
- E
  Emily CobbAug 21, 2025
  If your McCulloch Lawn Mower won't start, several factors could be the cause. First, ensure that the fuel tank is filled. If the engine isn't choked properly, consult the “TO START ENGINE” section in the Operation section. If the engine is flooded, wait a few minutes before trying again. Other potential issues include a bad spark plug (replace it), a dirty air filter (clean or replace it), a dirty fuel filter (replace it), or water in the fuel (empty the tank and carburetor, refill with fresh gasoline, and replace the fuel filter). Also, check for loose or damaged wiring. If none of these steps work, the engine valves may be out of adjustment, and you should contact an authorized service center.

How to troubleshoot a hard to start McCulloch M17538H Lawn Mower?
- C
  Christine MuellerAug 27, 2025
  If your McCulloch Lawn Mower is hard to start, begin by checking the air filter and clean or replace it if it’s dirty. A bad spark plug can also cause this issue, so replace it if necessary. Check the battery; if it’s weak or dead, recharge or replace it. Additionally, a dirty fuel filter can be the culprit, so replace it. If the fuel is stale or dirty, empty the fuel tank and refill it with fresh, clean gas. Also, check all wiring for any looseness or damage. If none of these steps work, the engine valves may be out of adjustment, and you should contact an authorized service center.

  If your McCulloch Lawn Mower engine clicks but won't start, the problem might stem from a weak or dead battery, so try recharging or replacing it. Another potential cause is corroded battery terminals, which you should clean. Also, check for loose or damaged wiring. If the issue persists, the solenoid or starter might be faulty, requiring a check and potential replacement.

What causes a McCulloch M17538H engine will not turn over?

  webbjamesAug 29, 2025
  If your McCulloch Lawn Mower engine will not turn over, make sure the brake pedal is depressed. Also, check that the attachment clutch is disengaged. If these aren't the issue, the battery may be weak or dead, requiring a recharge or replacement. A blown fuse can also prevent the engine from turning over, so replace it if necessary. Clean any corroded battery terminals. Inspect all wiring for looseness or damage. If the problem continues, the ignition switch, solenoid, or starter might be faulty and need checking or replacement. For faulty operator presence switch(es), contact an authorized service center.

  If your McCulloch Lawn Mower blades will not rotate, there might be an obstruction in the clutch mechanism, which you should remove.

Why does my McCulloch Lawn Mower have loss of drive?
- B
  Brittany BoltonSep 1, 2025
  If your McCulloch Lawn Mower has loss of drive, ensure the freewheel control is in the “engaged” position. If equipped, check for debris on the steering plate. A worn, damaged, or broken motion drive belt can also cause this, so replace it. If air is trapped in the transmission, purge it. Finally, check for a missing axle key and install one at the rear wheel.

  Your McCulloch Lawn Mower may be hard to start due to a dirty air filter (clean or replace it), a bad spark plug (replace it), a weak or dead battery (recharge or replace it), a dirty fuel filter (replace it), or stale or dirty fuel (empty the fuel tank and refill it with fresh, clean gas). Also, check for loose or damaged wiring. If the carburetor is out of adjustment, see the Service Adjustments section.

Why does my McCulloch M17538H Lawn Mower have a poor cut?
- L
  Lauren ReyesSep 6, 2025
  If your McCulloch Lawn Mower provides a poor and uneven cut, several factors could be responsible. Start by checking the blade for wear, bending, or looseness; replace the blade and tighten the blade bolt if needed. Ensure the mower deck is level. Remove any buildup of grass, leaves, or trash under the mower. Also, inspect the blade mandrel for bending and replace it if necessary. Lastly, check for clogged mower deck vent holes due to buildup of grass, leaves, and trash around the mandrels, and clean around the mandrels to open vent holes.

  yflynnSep 8, 2025
  If your McCulloch Lawn Mower experiences excessive vibration, it could be due to a worn, bent, or loose blade; replace the blade and tighten the blade bolt. Another possibility is a bent blade mandrel, which would need replacement. Also, check for any loose or damaged parts and tighten or replace them as necessary.
