#### 1. Increase the compression ratio.
This can be done by:
>* Milling the cylinder head
>* Installing a thicker head gasket
>* Using a higher compression piston
#### 2. Port and polish the cylinder head.
This will improve airflow into and out of the cylinder.
#### 3. Install a larger carburetor.
This will allow for more fuel flow, which will increase power.
#### 4. Install a performance exhaust system.
This will reduce backpressure and help the engine breathe better.
#### 5. Install a high-performance air filter.
This will allow for more airflow into the carburetor.
#### 6. Adjust the timing of the engine.
This can be done by advancing or retarding the spark plug.
#### 7. Use a higher-quality gasoline.
This will provide more energy and power to the engine.
#### 8. Check the engine's valve clearances.
Improper valve clearances can rob the engine of power.
#### 9. Check the engine's air-to-fuel ratio.
A rich air-to-fuel ratio can cause the engine to run sluggish and lose power. A lean air-to-fuel ratio can cause the engine to overheat and damage itself.
#### 10. Add a turbo or supercharger.
This will drastically increase the power of your engine.
