Toro Lawn Mower Engine Running Slow

It s new but the lawn mower loses power when cutting indicates some fixable troubles.

Toro lawn mower engine running slow.

By process of elimination most common problems can be identified in less than an hour by a moderately skilled homeowner. I have a toro model 20333 22in recylcler lawn mower with a briggs and stratton model 128t02 quantum engine type 3256 b1 code 11021759. It has been us. In fact clogging can occur in many areas of the lawn mower including the fuel line the gas cap the carburetor the needle and seat and the air filter.

Set the mower height as high as it will go and mow then come back in a few days and knock it down another notch or two until you get your lawn under control. Because a lawn mower is powered by a combustion engine that is powered by liquid fuel clogging is a major issue that slows down or even shuts down performance. From your description it sounds like you may have a problem with the governor spring that tensions the governor vane to the throttle body. The compressions system is made up of valves piston cylinders and rings that control how the air and fuel vapors move through the engine.

6 grass is a lot to ask from a mower. The important part is that each procedure step be fully executed thus eliminating some reasons for the malfunction. Start the toro lawn mower and let it idle for one to two minutes. The mower was purchased new in late march 2012.

My toro has the same engine and they are pretty quiet i see that as a big plus in my book. Turn the idler power screw 1 8 to 1 4 turn clockwise with a screwdriver until the engine begins to sputter counting the number of turns. Valves let air in the intake valve and out the exhaust valve pistons move back and forth pushing the air fuel mixture to the ignition system and the piston. If you have a really old one the lawn mower running slow and rough is normal.

But you expect smooth operation from a relatively new one. It happens every now and then throughout the entire life of a mower. In my experience unless the engine is running roughly idle problems are usually related to the throttle and governor. Troubleshooting a toro lawn and garden tractor is not a hard task to accomplish if the troubleshooting sequence is properly carried out.
