Whether you are thinking about converting your Craftsman lawn tractor into a racing lawnmower or just trying to make it go faster, you will have to do several specific alternations to achieve your goal. The engine on your Craftsman lawn tractor has several safety features that prevent your engine from going faster than the manufacturer recommends. Still, there are some things you can do to your Craftsman lawn tractor to ensure maximum speed.

Shut off your Craftsman lawn tractor. Open the bonnet.
Examine the muffler and the exhaust pipe connected from the top of the muffler to the side of the engine. The muffler is bolted to the front of the Craftsman lawn tractor frame. Inspect them for cracks or holes. Cracks and holes in them can reduce engine back-pressure and therefore lower the engine power and speed. Replace them if they are cracked--they are both held on by just four bolts.
Unscrew the bolts holding the flywheel housing to the top of the Craftsman lawn tractor engine with the proper-size wrenches. Under the flywheel housing is a small plastic flap bolted next to the flywheel. This is the governor, which prevents the engine from running too fast.
Remove the governor. Unscrew the single bolt holding the governor to the top of the engine block. Unhook the two springs from the governor to the carburettor and throttle.
Replace the flywheel housing by bolting it back into place.
Fill the Craftsman lawn tractor gas tank full of 92 octane gas. Higher octane fuel burns faster and will make the Craftsman lawn tractor go faster.
