Why Toro 22198 engine does not start?
- C
  cindy13Aug 8, 2025
  Your Toro Lawn Mower engine might not be starting due to several reasons: the fuel tank could be empty or contain stale fuel (in which case, drain and refill with fresh gasoline; if the problem continues, contact an Authorized Service Dealer), the throttle lever may not be in the Choke position (move it to the Choke position), the wire might not be connected to the spark plug (connect it), or the spark plug could be pitted, fouled, or have an incorrect gap (check and adjust the gap, or replace the spark plug if necessary).

Why Toro 22198 engine runs rough?
- J
  Joshua FisherAug 12, 2025
  A rough-running Toro Lawn Mower engine may be caused by the wire not being connected to the spark plug (connect it), a spark plug that is pitted, fouled, or has an incorrect gap (check and adjust the gap, or replace the spark plug if necessary), the throttle lever not being in the Fast position (move it to the Fast position), or a dirty air filter restricting air flow (clean the air filter pre-cleaner and/or replace the paper air filter).

What to do if Toro 22198 does not self-propel?
- B
  Bryan SmithAug 16, 2025
  If your Toro Lawn Mower is not self-propelling, the self-propel drive cable may be out of adjustment or damaged (adjust the self-propel drive cable, replace the cable if necessary), or there may be debris under the belt cover (clean the debris from under the belt cover).

What to do if Toro Lawn Mower engine starts hard or loses power?
- K
  Kyle RodriguezAug 20, 2025
  If your Toro Lawn Mower engine starts hard or loses power, it could be due to stale fuel in the fuel tank (drain and refill with fresh gasoline), a dirty air filter restricting air flow (clean the air filter pre-cleaner and/or replace the paper air filter), clippings and debris under the lawn mower deck (clean the underside of the deck), a faulty spark plug (check the spark plug and adjust the gap if necessary, replace if pitted, fouled, or cracked), or low/dirty engine oil (check the engine oil; change if dirty or add if low).
