If you neglected to add gasoline stabilizer to the fuel prior to storage, empty the tank and replace with fresh gas. If the tank is nearly empty, simply topping off with fresh gas is often enough to get it started. On some mowers, you can easily remove and empty the fuel tank.
With the leaves changing colors, it is time, almost, to put the gas-powered lawn mowers to rest for another winter. Prior to storing the lawn mower, it is a good idea to remove the remaining fuel from the fuel tank and dispose of it properly.
If there`s only a little fuel left after the last mow of the season, your best bet is to run the tank dry. If the tank is full or nearly full, disconnect the fuel line at the carburetor and drain the remaining gas into a gasoline storage container. (You can add the leftover fuel to your car.)
Everything from the tank to the carburetor and injectors will be cleaned out when using STA-BIL Fast Fix. This formula is compatible with all gasoline small engine equipment. Just pour in the tank and be on your way.
Fail to use fuel stabilizer can mean poor performance or an engine that fails to start at all after several months of storage.
Water in the engine is a killer.” Smart move: At the end of the season, take 10 minutes to drain the tank or run the engine dry. Never change or add oil. Moving metal parts need oil, and an engine that`s denied clean oil, and enough of it, will overheat for sure.
One of the easiest ways to maintain your snow blower or lawn mower engine for seasons to come is by using fuel stabilizer. Whether putting your lawn mower or snow blower away at the end of the season or letting some time pass between uses, curbing your fuel`s degradation is crucial.

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!!!

Lawn mower cranck but wont start…
ANSWER : Since you already checked for spark and air I would drain all the fuel out of it and check that fuel for water. Over time some lawn mowers end up with contaminated fuel. You can see the water sitting on the bottom of the fuel if you let it stand for a bit in a small plastic bowl.

Be sure to empty and dry out you fuel can as well. Especially if the mower stopped running right after a refuel. Which is a good sign your gas can is contaminated too.

Wont start no ignition put new plug in and fuel filter
ANSWER : Flush gas tank, fill with fresh gas and Stabil. Replace air filter. Remove bowl from carb clean bowl and holes in bowl screw.
