Easiest way is to slap on the dual port. Carb adjustment will have to be done, yes. But in an ideal world, you should be adjusting your carb almost every time you use the saw. Environmental conditions are never the same, day to day. High performance engines that pull every last bit of power out of combustion, need to be perfectly tuned.
See it like a dragster vs. a daily driver. The daily driver doesn't need a tune but once every couple years (pre-computer days), as it's tuned for general use and makes enough power to get the job done. A dragster is tuned every time it's used, for specific environments, etc. - trying to get every ounce of power you can. I view small 2-strokes the same way. I try to have my saws running 100% perfect every time I use them. It only takes but a couple seconds to tune it - less than a minute really.
