That particular engine is good except the carb. The carbs were poor copies of OS and ASP years back. I would say 60%+ of the carbs are fine. If you're picky, then purchase a known brand carburetor or one from RJH (K&B, Machoa - US made) and it will perr... The cylinder and everything elese were awsome for the price.
