I have a 1994 Force 9.9 hp (model 225.581996) kicker...this motor came from sea level and I am located at almost 6000 feet in altitude. What adjustments do I need to consider before running it? I know my big motor required rejetting, a drop in prop pitch and a timing advance...what about these small engines?
