Give me a minute to grab my sheet. I have one of these and it's a great engine.

Here's a question for you! My O.S. 61 FS runs great on the high end but is rich on the bottom and I can not lean it. I have cleaned the carb. Adjusting the bottom doesnt change much except that too far in and it dies or to far out and it dies. It remains rich! Any ideas?

Thanks,

Danny
