RE: Fuel for old engines
That is the motor, not the fuel. They are ALL individuals and no two are exactly alike in their habits. The Mills diesels as a general rule are the closest I have ever seen to being a family group. You put it in a plane or on a stand, put on a prop, add fuel, flip and off you go. Every single one I have tried is like that. The ED's are a close second but more high strung.
