RE: Calling all small engine Guru's- Ryobi help needed
How far can you reduce the throttle before the rpm starts to drop, if you reduce the throttle opening, say 25% before the rpm starts to drop, the carb could be too big. I used the stock Zama carb off of a Ryobi 31 on my OPS 30 Maxi when running it on gasoline and it was perfect for it.
