I have been told that if you open the reed value 1/8" on the ryobi carb mount you can will get an additional 400 rpm. Do you bend the reed value itself or do you bend the reed value stop.

Thanks

Bend the reed valve stop so it allows the reed to open 1/8". Don't bend the reed, It should lay flat on the backplate/manifold.

Thanks for the input. I plan on testing this, this weekend if it does not rain here in Memphis. I plan on using an 18x8 prop on it so I was hoping to get as much rpm as I can. My plane will weigh in around 16 1/2 lbs with 1276 sq in wing area.

Thank again

Hi:
If i understood right the metal piece to be bend is the little one over the flat one that should lay flat.
Is the success enought sure to do that or the amount of bent is too critical???

Thanks for the help, nice thread

Well if you bend it too far you run the risk of damage as the crank will srtike the reed stop. I bend mine with the jug off so I can bend it to just about too far and see it for myself. Piper

On both my Ryobi 31CC short shafts, the reed's back stop were already set by the manufacture at 1/8 inch above the reed. Did anyone else take notice to what their gap setting was prior to increasing it?
