Default RE: Calling all small engine Guru's- Ryobi help needed
7900 rpm is very high for a Ryobi with a 18-8 prop. It would take a lot of modification for one to ever achieve that. A stock Ryobi turns a 18-8 about 6900 rpm.

Some Ryobi's had a coil with a rpm limiter in it that wouldn't let the engine run well beyond 7000.

Normally, the biggest effective carb venturi size for this engine would be 7/16" . The Standard carb from the factory is 5/16".

Just thinking
