Why is my Toro 30455TS Lawn Mower engine emitting smoke?
- R
  Robin WeaverAug 22, 2025
  If your Toro Lawn Mower engine is emitting smoke, several factors could be responsible. It may be due to air getting into the feed system, so check the gaskets and pipes. A defective fuel supply could also be the cause, so check the filter cartridge. Other potential issues include incorrect pump timing (correct the timing), incorrect spray or injectors out of adjustment (check, clean and adjust injectors), air intake restriction (check hoses and air cleaner). Insufficient automatic advance or high discharge rates may require you to have the pump repaired.

  If your Toro Lawn Mower engine lacks power, the issue could stem from several causes. It may be due to a defective fuel supply, so check the filter cartridge and pipes. Alternatively, the pump timing might be incorrect, or the spray and injector pressure could be out of adjustment; in this case, check, clean, and adjust the injectors. An air intake restriction could also be the culprit, so inspect the hoses and air cleaner. Finally, insufficient automatic advance or low discharge rates may require you to have the pump repaired.

  Tyler RiceAug 27, 2025
  If your Toro Lawn Mower engine is noisy and stalls while idling, it could be due to several reasons. Incorrect pump timing could be the cause, so correct the timing. Blocked or overly advanced automatic advance may require you to have the pump repaired. Air getting into the fuel system, which means you should check gaskets and pipes, or an idling stop out of adjustment, so adjust idling stop, could also be responsible. A jammed discharge rate may require you to have the pump repaired.

Why is the maximum speed too high and the engine will not accelerate on my Toro Lawn Mower?
- J
  jason63Aug 30, 2025
  If your Toro Lawn Mower has a maximum speed that is too high and the engine won't accelerate, it could be due to several factors. The maximum speed stop may be out of adjustment, or the discharged valve might be jammed, which means you will need to have the pump repaired. Additional causes could be a blocked pump governor, a defective fuel supply (check filter cartridge and pipes), a seized pump plunger, a broken pump plunger spring, or a hard discharge valve; these issues may require pump repair. A seized feed pump may require you to drain water from tank, pipes and filter and have pump repaired. Finally, the accelerator linkage could be defective, so repair the linkage.

  If your Toro Lawn Mower engine is vibrating, it could be due to unequal discharge rate, which means you will need to have the pump repaired. Alternatively, there may be air in the fuel system, so check fuel lines and clamps. A defective fuel injector, so check injectors, or a jammed discharge valve, which means you will need to have the pump repaired, could also be the problem.

Why will my Toro 30455TS Lawn Mower engine not start and emits black smoke?
- J
  Jaime NewtonSep 2, 2025
  If your Toro Lawn Mower engine will not start and emits black smoke, it could be due to several reasons. The air intake may be obstructed, so check air intake. Defective injectors may also be the cause, so inspect injectors. A lack of compression (seized rings, damaged or worn valve seats, or general wear) is another possibility, so check compression. Lastly, the injection pump timing might be off, so adjust injection pump timing.

- A
