If you read what I posted in Post # 439, you will see that I really don't recommend converting glow engines to gas, though converting them to Gas/Glow would be slightly better since Gas/Glow does run a little cooler than pure gasoline.

But, if you are determined, the Ryobi trimmers come with a quite small Walbro carb. The original carb won't work well with gasoline and will be difficult to adjust. There is another thread here in this forum where some guys are converting glow engines to gasoline.... You might get some ideas there.
