How can I increase the horsepower of my small engine?

increase compression
. Your engine will be more powerful if you build compression. The most common way to make power has never been more common sense than internal combustion. Make sure you don't raise compression too high.

air intake or fuel system related
.

Why is my riding mower so slow?
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
. 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.

Very low RPM cap
, around 1,800 rpm is all they are rated for. That said, they make very little horsepower, but massive amounts of usable toque from idle to rev limit.
How do I find my tractor torque?
When you choose torque, this calculator will measure the approximate torque of an engine
based on the horsepower, multiplied by 5,252 (conversion between foot-pounds and horsepower), divided by the RPM of the engine
. For example, if your engine has 350 horsepower then the torque would be 367 foot-pounds, at 5,000 RPM.
What causes torque to increase?
Torque can be increased in two ways: 1) by
increasing the moment arm
or 2) increasing the perpendicular force applied to the moment arm. The opposite is true for decreasing torque. If an object is at rest the torques on the object are balanced (they cancel out) and sum of those torques is zero.
What does a governor do on a lawn mower?
The governor system is like a cruise control system. It
maintains the speed of your lawn mower or outdoor power products
. When Briggs & Stratton governors are adjusted properly, they keep your speed steady regardless of engine load – the amount of work the engine must perform.

. You want to make sure the cables connected to the spark plug don't become loose and move unsteadily in a particular direction. Apart from that, check inside the spark plug if there are any corrosion build-up issues.
Why is my riding lawn mower revving high?
Airflow Issues
A lawnmower that hunts and surges may be experiencing something as simple as an airflow issue. If the air that the engine requires to run is blocked, especially sporadically, it can cause the engine to slow down. When the blockage moves or clears, the engine may suddenly rev up in response.
How do I stop my lawn mower from sputtering?
Your mower pulls in air from outside and mixes it with gasoline for the proper explosion inside the engine. A dirty air filter inhibits the flow of air into the carburetor.
Clean or replace the air filter
to stop the mower from sputtering to a halt. Too much air can also cause problems for the engine.
