    Is it possible to tune a carb that is designed for a 35 cc engine to run on a 25 cc engine? I am considering reviving an old FS85 since I have a carb that physically fits on the engine. Just wondering if anyone has done it?

    If it will fit I'd say just go ahead and put it on. I don't know for sure but it may be the exact same carb. I know I mix and match carburetors on push mowers all the time and they work just fine. Hope that helps. :)

    It should work, but you will need to adjust the mixture screws, which you probably would do anyway.
