If it runs good, the carbs are probably ok. I'd still pull the plugs and look. Also, check the date codes on that "new" rubber and makes sure that they aren't old. They are probably fine, but check because it's so easy to do. Just because they have good tread doesn't mean they are safe. If you dont know where to look, do a google search, or search on this forum. I know its been discussed many times here.
Sounds like you have a winner. What model and what are they asking for it?
