Ryobi 700r Gas Trimmer Parts Help Needed

[NO0C]

Thanks for all the help guys. The Walbro WT658 replaced the Zama with no problems. Really the only thing you can set is the idle speed. The low idle screw has virtually no adjustment to it and of course there is no high speed mixture screw.

Purrs like a kitten and runs like a scalded dog.

Now to figure out how to make the bump feed work as advertised. It's sure not a Stihl !

Thanks again to all.
