Ok, so hears a question, how rich is too rich? My engine is running a 20:1 gas/fuel mixture the needle is @ the 2nd to the bottom notch. I leave a trail of smoke even at 20 Mph! Do I need to run this rich, even though these are scavenger engines and I run wide open 70% of the time? How rich do you run? FYI I am in a semi-desert so dust storms are often, and have an altitude of around 1472 meters (4829 feet), I also have about 150 miles on this engine.
