Toro 20056 Repair

Check the fuel level of your Toro 20056 push mower and ensure it is adequate. Fill up the gas tank if you are out of gas.

Rid your Toro 20056 push mower of old gas that may have been left in the Toro from a prior season. Add just enough fresh gas to the mixture to start the engine, then leave it idle so all the unwanted, old gas burns away. Fill the tank up with fresh fuel.

Open up the engine cover of the Toro 20056 push mower. Use a socket wrench to remove the three bolts holding the cover in place.

Check the Toro 20056 push mower's pull rope. If it is broken, you will need to take it into a lawn shop for repairs.

Ensure the plug wire at the front of the Briggs & Stratton engine assembly is connected into the spark plug if the mower still won't start. Reinsert this thin, black wire into the Toro's plug wire if necessary.

Replace the spark plug altogether, as it may have gone bad over time and many uses. Visible corrosion, wear and a blistered white insulator ring at the end of the spark plug indicate a faulty plug. Remove the plug wire from the back of the spark plug and reinsert it into your replacement spark plug. Visit your local lawn care shop or Toro dealer for this replacement.

Find the mower's air adjustment valve. This is on the carburetor. Turn the valve to the right until you can turn it no further, then turn it back to the left two turns. Attempt to start the engine again. The air adjustment valve controls how much air goes into the carburetor and there may have been too much or too little air entering, leading the engine to run incorrectly.

Adjust the air adjustment valve to the right and left several more times if the engine continues to run rough. Test the mower.

Unscrew your mower's fuel tank cap and check the small vent hole on it. If this is clogged, air will not be able to enter you gas tank and this will limit the flow of air to the carburetor. Use a small pipe cleaner and force the clogged mess through and out of the vent cap's hole, then wipe any additional debris up and off the cap with a damp cloth.

Replace the fuel tank cap.

Set the engine cover back into place using your socket wrench.

Remove the bowl on the bottom of your carburetor if it is sputtering, as the inside of the carburetor may be plugged. Loosen the bowl's nut using a socket wrench and allow the gas to drain out. Have a pan in place to catch the gas.

Wait until all the gas drains and then remove the nut entirely and take off the bowl. Wipe out the bowl with a cloth and soak the nut in carburetor cleaner. Use a soft wire brush to work around the small passages of the nut to clean out any build up.

Put the bowl back into place and tighten the nut within it.
