Why won't my Snapper 150Z ZTR Lawn Mower engine turn over?

  The engine might not be turning over due to several reasons. Ensure the ignition switch is fully turned to the START position and the ground speed levers are set to START/PARK. Also, the mower blade switch should be in the OFF position. Check and clean the battery terminals if they're dirty, or recharge/replace the battery if it's discharged or dead. Inspect the wiring for any loose or broken connections and tighten or replace as needed.

What to do if Snapper 150Z ZTR engine turns over but won't start?
- D
  Daniel FrenchAug 3, 2025
  If your engine turns over but doesn't start, the choke position might be incorrect. If the engine is cold, move the choke to the CLOSED position. If the engine is warm, ensure the choke is in the OPEN position. If the engine is flooded, set the choke to OPEN when cranking. Also, check if you're out of fuel or if the fuel is old or stale; refill with fresh fuel if needed. Inspect the spark plug(s) for fouling or incorrect gapping; clean, gap, or replace them.

  If your Snapper Lawn Mower engine starts hard or runs poorly, the air filter might be plugged. Service the pre-cleaner and/or replace the air filter element. Also, make sure the choke is set to CLOSED when cranking a cold engine and OPEN after the engine starts. A warm engine may not require choking. Check the spark plug for issues; clean, gap, or replace it if necessary.

  Black exhaust from your Snapper Lawn Mower engine is often due to a dirty air filter or pre-cleaner. Service or replace them as needed. Also, ensure the choke is set to OPEN as soon as the engine starts, not left on CLOSED while running.
