Since the truck is new to you, if it's been running OK then I would probably assume that the previous owner tuned the carb right until I saw evidence to prove that wrong. You may find that the PO went through the whole process of re-jetting the carb and making it right. I'd probably invest in the rebuild, then see where I stood relative to plug color, response, mileage, etc. An easier way might be to just buy a new 600, but I tend to be a bit frugal.
