my F2400 (3400 hrs) just broke. Two days ago the engine started making loud banging noises and smoked. I'm getting too old to do major work so I'll be parting out. F2400 has 100% parts at present. I also have an F2000 that I ran for years until the head cracked ( have a complete new head that I never installed). I have both working 60 and 72 in side discharge decks. I'll start the parting out process
