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.

that's the whole kruks of the matter, our smaller glow engs. MUST HAVE AT LEAST A LOWER ROD BRG. for the eng. to last any time at all running on gasoline/oil and most just don't have big enough end of the rod to machine & fit a caged roller brg. in it. some guys are converting S.T. .90's and some larger engs. with some success. 4stks are just not a good candidate at all!!!!!![&o]
and 1 more thing, as far as fuel costs go, most of our 4stk eng. and pretty [sm=thumbup.gif]stingy on fuel anyway.
