Re: Honda mixture?
I'm familiar with high altitude running characturistics in general.<br />The difference of a sea level and 6700 ft. is substantial. Hot and cold starts, idle quality, and economy will suffer without adjustments. Oil contamination might also be an issue.<br />These adjustments should include a precise and complete (valve adjustment) major tune-up, mixture and carb balance adjustments and a slight increase in base idle. Lube and maintain the choke selenoid plunger with light oil.<br />This may be all that is needed. However, if the motor is living at that altitude now; I would investigate a jetting change in the carbs. And Honda may very well offer a high altitude kit for your application.<br /><br />You will notice operating characturistics just as with your other vehicles. Although modern fuel injection takes care of most of these concerns, all enjines suffer from high altitude operation.
