Change to Synthetic Fuel
Hi i have always used duraglo 5% which is a castor based fuel but i have decided to turn to fully synthetic fuel for cooler running and less mess i have just purchased 3 gallons of Model technics Fourmula irvine Sport 5% which contains 18% klots question is i heard you have to be more careful about running lean so should i richen it up a bit before starting with the first tank?
