Re: Ryobi 4 Cycle Trimmer Run Issue
Make sure your fuel cap isn't causing an issue. Check the exhaust port and muffler. Make sure they're not restricted. And I agree, it definitely sounds like fuel starvation. And make sure you have the fuel lines on the right connectors. I would say you probably need a carb adjustment, but since you already replaced it, you should have noticed a difference. Might not have run perfect without a little tweaking but usually a noticeable difference.
