if you want to bore out a carb with a hole saw go ahead.  we're not stoping you, its just not how you do it.  a dremel and sanding drum would come out better. 

i don't have a bad attitude, i hardly post anything, think the last thing i posted that was negitive was about Q 5 years ago.  you just come off as the smartest guy and your asking a stupid question.  your gonna get this kind of reply.
