Ryobi string trimmer issues

I acquired a older Ryobi trimmer, in very good condition, and am hoping ya'll can help me out to fix it. It does start and run BUT as soon as you hit the throttle it dies. I have put in fresh gas, new plug, cleaned the filters, replaced gas lines. The previous owner messed with the air/fuel mixture screws so I am wondering where to start adjusting those to factory settings?? If I turn them completely in...how far out should they be turned??

When it starts it runs a little high on the RPM's as it is right now. So I know the screws are way out of adjustment. But as soon as you touch the throttle....it quits. Any help will be appreciated.

Try with them turned out 1 1/2 turns from lightly seated and fine tune from there. It sounds like it may need a carb cleaning/rebuild. See if it will rev up if you back out the high speed screw (the one closest to the air filter) a little.

Started messing with this today. I readjusted screws to 1 1/2 turns out but now am having a hard time starting. When it did finally start....it would only run at 1/2 choke. Full choke it would quit. It also did rev up better than it has.

I only see 3 screws on this. 2 are on very top by choke. There is an access slot at mid choke to get to them. Then on right side toward bottom by muffler there is an idle screw. I am assuming the screws at top....closest toward shaft is actual air mix, and 1 toward muffler is high rev speed you mentioned.

What I actually have is a Ryobi 700R if that helps any.
