Just purchased a 2007 430 with 190 hrs. I live at 9,000 ft elevation, the unit seems to backfire/miss when it is put under a load. Puffs out pretty dark when it mis-fires. Unit has a new fuel filter, treated fuel. Is there some kind of adjustment for high altitude? I noticed that in the case parts manual there is reference to a mis-fire upgrade kit, what is it and do I need it. Thanks for your help
