I have never heard of any single cylinder engine having worse gas mileage than another of the same model to any extent that would be noticable. That is if your machine is stock.

Just do a tune up. Clean your air filter, new spark plug,change your oil and oil filter, flush your gas tank if it's a few years old and you haven't done it yet.
This probally wont make a difference, but it isn't going to hurt anything for sure.

You haven't been tinkering with the carburetor adjustments have you??

 

nope haven't been messin w/ carb

 

Light it on fire and buy a faster one.
