I bought a Saito FA-80A the other day really, really cheap (it's a Golden Knight, too). It's missing the high speed needle. Is this a generic item, does one size fit all, or are they specific to a series, or a specific carb model? This engine is almost new; it's in the original box, has the old style billet muffler and elbow header, all the valve adjusting tools, etc. From the looks of the finish, it's had very little run time. I can't find a series letter on the mount flange like all my other Saitos have; it's an old enough model that it still has the choke plate, but new enough that it is not an air-bleed low-end carb. I know this engine has been replaced by the .82, but for $105, I wouldn't pass it up just because it's discontinued. I like the longer stroke brass sleeved Saitos, anyway. What can anybody tell me about the needle?
