I just happen to find your website. Very Interesting. I have had this JD mower for over 10 years, and never any trouble. I know that the BBC needs to be replaced. The local JD dealer wold repair for $200 parts and labor. Can someone tell me if it's hard to replace yourself. I think it comes as a assembly kit, and I'm thinking about trying it. I'm worried about springs flying everywhere and ending up with a mess. Any help would be appreciated. Thanks.
