Bob,
I just got my Pilot EXTRA 260 30% completed with a DLE 55 for my first 55CC. I thought gas was going to be this huge learning curve. The DLE makes it so easy. I just started flying it and already have 2 gallons through it. I haven't touched anything on it from the box it runs perfect. I have been running Lawn boy through it but I don't think it matters. The engine and plane are unlimited!!!!!!! Go for it you will love it.
