i have a almost new Alpha 40 with evolution training system engine.I hung it up in my garage and ive notice fuel is leaking behind the prop or directly in front of engine.Is This normal or have i got a seal out? Also if it needs repaired is a big process?

The seal on that front bearing will and can leak, especially in the vertical hanging situation. I have mine like that all the time. I just use a piece of plastic sheet under the spinner to catch the drips. I have 2 of the engines, they both do it. Nothing to worry about. [8D]
