How much cc are in a 6 horse power engine?

There are many ways to make horsepower. Compression, carburetion, stroke etc. A smaller engine may make more horsepower than a bigger engine. So trying to find the cc from a HP rating is guessing at best. To give you a ball park figure I just looked on a Tecumseh 6HP Power Sport engine and it says 195cc on the manufacturers tag. Hope this helps.
