We have a 1998 of the same. Best motor ever, had it for five years, never put a spanner on it. Starts third pull on cold start, first after that. I would love to know how many hours we have clicked up on it.
Will never sell it, best motor on / in anything we have ever owned and we bought it second hand. The guy I bought it off still asks if he can buy it back.
Like a good dog, only come along once or twice in a lifetime.
Don't sell it!!!!
