9. TWO STROKE ADVANTAGES Is less expensive because of its simpler design.
The engine fires - spark plug ignites - once every revolution of the crankshaft.
They produce twice the power than four stroke engines.
Packs a higher weight-to-power ratio because it is much lighter.

10. TWO STROKE DISADVANTAGES
They last less. Lubrication is not as efficient as in a four-stroke engine with heavy oil.
Do not use gas efficiently.
Pollute more.
Faster wear and shorter engine life than a four stroke due to the lack of a dedicated lubricating system.

11. FOUR STROKE ADVANTAGES
Last longer than two stroke engines
More efficient use of gas
Pollute less than two stroke engines

12. FOUR STROKE DISADVANTAGES
More complicated. Many more parts to worry about.
Half as powerful as two stroke engines (for equivalent engines)
Fires once every two revolutions.
