Just to be sure that I understand what the manual is saying. My 48cc Skyhawk book calls for 16/20:1 gas to oil for the first 4 tanks. After that they say 20/25:1 gas to oil. Seems pretty straightforward. Then it says "In hot climates or long trips use a rich oil mixture". I have always equated a "rich" mixture to mean more gas than the air would handle. Simply put "do they mean more like 16/20:1 as in break in or 25+:1 ratio." It gets pretty hot here in AZ. and I don't want to cook my new toy. Thanks.
