Default Re: Why is 48cc more powerful than 66cc

I'm led to believe that the 48cc will rev higher than the 66cc, resulting in a marginally higher top end. I'm also led to believe that the base carb that comes with both the 48 and 66 kits is more appropriately "tuned" for the smaller engine. (The throat is too small for the larger engine to breathe properly.)
