RE: Great Planes RV-4 .60
Sounds like you're not going to have any trouble at all. Just remember that the ring in a DLE is very hard, so it takes a long time to seat. 4-5 gallons is not unusual for FULL break-in. Fortunately, as soon as you get the needles set after it's first start, you can fly the snot out of it. Break-in is best done in the air. Better cooling, for one thing and a hell of a lot more fun, too!
