If the muffler on the lawn mower is blocked, the engine will run rough and/or die. The engine stalls because the it cannot expel burnt gases that build up as it runs.

Hp Out Of A Lawn Mower Engine

When you want to get more horsepower out of your lawn mower engine or if you want to turn it into a racing lawn mower, then you will need to take some specific steps to optimize your mower engine 's horsepower. Remove the flywheel housing from the top of your engine. Unscrew the bolt holding the governor flap next to the flywheel with the proper sized wrench. When the lawn mower engine spins too fast, the governor flap blows out and slightly closes the carburetor, therefore decreasing the speed and horsepower of the engine. Check that the muffler is tightened to the engine block and the gasket is whole--there is a gasket between the muffler and the block. If the muffler is cracked, buy a new one and install it. They are fairly inexpensive and you only have to remove three or four bolts to install one.
