Ryobi tp30. Starts ok. Will not run as throttle revs up. Idles fine. But rev it up it stalls.

SOURCE: Hedge trimmer starts fine then stops after 5 minutes

Carburetor high speed adjustment ( screw nearest the filter ) open ( counterclockwise ) 1/2 turn.
Adjust again as needed to run when hot.
make sure the gas mixture ratio is as required.

SOURCE: My Ryobi weedeater engine keeps stalling out.

Here was my solution:
I was having problems with my ryobi cs30 weedeater also. It would start up fine on full choke, but i could not give it more than half throttle or ever take the choke off or it would stall out. I replaced fuel mixture, spark plug, spark arrestor/exhaust, fuel lines, cleaned carb, and still nothing! I was considering getting a better machine. Then i decided to play with the carb adjustments.(on my cs-30, they are two screws on the carb that have a "L" and "H" next to them) I dont think you can get the specialty tool for adjusting the carb unless you are a repair tech, so i just took a Dremmel tool with the circular cut-off wheel to the head of the specialty screws and made them into "flat-head" screws so i could adjust them with a regular screwdriver (if you dont have a dremmel too, get one!) (As i was cutting into the head of the screws, i also cut into the casing protecting the head of the screws that was in the way, this does not cause any damage to the unit, that casing is only there to keep "un-certified" people from adjusting it for themselves.)
Now to the easy part: The "L" screw adjusts the idle fuel mixture and the "H" screw adjusts the full throttle fuel mixture. turning the screws clockwise make the machine run leaner (less fuel) and counter clockwise makes it run richer (more fuel).
-I started out by turning each screw 1/2 turn counter clockwise and started it up, then as it was idling, i started adjusting the "L" screw as i was moving the choke position to run, after a few full turns counter clockwise of the "L" screw, it was idling perfectly in the run position, then i did the same thing the the "H" screw while holding down the throttle and i got it to run perfectly in the run position. Now it is running way better than it ever has. I hope this helps everyone.
Good Luck!

You need to rebuild the carburetor. You will need to go to an outdoor power & equipment store of some kind to get a carburetor kit for your specific trimmer. It will come with various gaskets, (some of which you won't use), a needle valve, and a small screen that goes in the carb. Replace all old parts with new. New primer bulb is sold seperately. When you have the carb. apart, you will also need to clean the small ports with a Den Tek Brush (used for cleaning teeth). Use carb. cleaner when cleaning.

some carbs are not adjustable,check your air filter first to make sure its not rescricted and also a new plug,make sure your fuel is fresh,now if you do have adjusting screws,most have plastic caps on them with preset adjustments locked in,you will have to remove these caps to adjust,they need not be reinstalled,Hope this helps

Sounds like the air screws need adjusted on the carburator. If there are 2 the one with the L above needs to be turned althe way to the right but not to tight and then backed out 1/2 turn to left. The one with the H anove it do the same except back it out 1 and 1/4 turns to left. If it only has 1 screw dot he same but back out 2 complete turns. Hope this helps?
