the magneto? Is this simple?
Power Lawn Mower

Experienced gardeners share their insights in answering this question :
You may not need to change the ignition module. The “air-gap” on it may just need to be adjusted. That is, the distance between the pickup legs of the ignition module and the magnets integrated into the flywheel. You would have to remove the exterior cover and any sheet metal cowling (directs air flow off the flywheel around the engines cylinder). Then, the coil and flywheel should be visible. I use a standard business card as a gauge. Slide it between the coil legs and the magnet area of the flywheel. You should feel just a slight little rub. If it won’t slide or the gap is large, no spark will be produced. You will have to loosen the screws holding the coil in place, double up the card. let the magnets pull the legs in against the card with magnets behind and retighten. Then recheck for spark. Post back if needed.

An airlock is one of the common causes why your mower won`t start after running out of fuel. An Airlock occurs when air replaces fuel in the fuel lines. As you refill your fuel tank, you could push the air towards your mower`s carburetor, which keeps the new fuel from reaching the engine.
There may be a problem with the fuel, the filters may need cleaning or replacing, or the spark plug may be bad. Moreover, if the recoil or electric starter is malfunctioning, the engine may not be spinning fast enough to turn over.
Loose, Dirty or Disconnected Spark Plug in Your Lawn Mower: Check it out, clean off debris, re-connect and tighten. Dirty Air Filter: Clean or replace. Fuel Not Reaching the Engine: Tap the side of the carburetor to help the flow of gas. If this doesn`t work, you might need a new fuel filter.
Your lawn mower turning over but not starting due to several reasons, such as a faulty or disconnected plug, a disconnected spark plug wire, a clogged air filter, or a contaminated fuel tank. A faulty carburetor, a dirty cutting deck, or a dysfunctional flywheel brake can also cause this.
A dirty filter chokes off air to the engine making it hard to start so check to see if yours needs to be replaced. If you need a new filter be sure to use the original manufacturers part or the correct Toro replacement. These can often be purchased at your local Toro dealer or a home improvement store.
A Dirty Carburetor Can Cause a Lawnmower To Start Then Die

By far, the most common issue that causes a stalled motor is a dirty carburetor. The carburetor on your engine is the thing that draws in air and mixes it with the fuel. Contrary to what the movies might make you think, gasoline itself is not very flammable.

I have trouble starting a toro walk behind mower
ANSWER : All, I thought my carb was shot, so I replaced it. Still, start but no run (and had to use starting fluid). THEN!!! I noticed the spring to the “rev limiter” (just below and towards rear of carb) was not “tight”. The stupid bracket that holds the end of that spring had been bent down ~1/16″ and that caused all this heartache. CHECK YOUR REV LIMITER!!!
