should i get a professional to re-tune my carb? or is it something i probably could do on my own?

 

You should be able to do it on your own without too much trouble and a bit of knowledge. Just learn how changing the jets/air bleeds effects how the carb regulates the fuel flow and you should be fine. It's just trial and error until you find the perfect combination.

 

Yes, do an internet search, you'll find lots of info to point you in the right direction.
