Many small line trimmers lack a clutch system by design so this could be normal.

Ryobi trimmer Rlt30CES head slow down under revs

Sounds like a drive shaft/clutch type problem, I do not know the machine but suspect it uses a flexible shaft to the head has this union worn out or at the motor end there would be some kind of clutch which would leave the motor spinning on tick over (not the head) then engage on rev up. Perhaps this is faulty or has oil on it, could be its flexible shaft has got a worn end.

On my old B&D it throws a sprung disc out under centrifugal force to engage with its drive shaft coupler which at low revs the springs "win" to disengage it.

Its head end is easier first to check by removal of its line holder after that things are more complex with mine four screws remove what I call its nose cone to get into the clutch area.

If there is a wear issue run it at a gentle speed dabbing its head into some grass you may find the motor spins on but its head stops which will confirm the above.

Hope this helps..........

I hsve a ryobi brush cutter when i tighten the carburator screws it does not want to start when i loosen them it starts can someone help

You have to adjust them properly.

Turn in both needles clockwise til snug, not super tight.

Now back each one out counter clockwise 1 full rotation

Now the L needie you adjust while the unit is just idling,
If it doesn't idle yet, back it out in 1 quarter turn increments

Once you have the unit idling where you it's running fine, basically if the brush cutter head is spinning while idling, you went too far...if it's not, it's right..

The H needle you do the same thing ONLY difference is whwn you adjust this needle you have to hold the trigger in the whole time you're adjusting it...

Ryobi s430 will idle but will stall out when throttle opens. This carburetor has one idle adjustment screw and one fuel mixture screw.

Those carbs are a pain. Try arousing the idle screw, turun it to the right, then try to see if it will idle. You will have to tinker with the adjustment screw and the idle screw. Eventually you're gonna need a new carburetor. You can rebuild it, BUT , chances are those cheap carburetors never are the same.

2003 1500. Why won't it idle?

Have you tried adjusting the idling speed manually via the carburetor setting? You could also consult the Haynes manual -- see. Haynes is the information resource for the DIY enthusiast

What is the factory carbuerator settings for ryobi cs30 weed eater

The Walbro WYC-9 only adjustment is the idle speed. This is just slow enough for the trimmer head clutch to disengage.

Idles low and ruff with a slight miss, but not sure where to adjust the idle at.

The idle adjust screw is usually accessed from under the carbs, usually in between the #2 & #3 carbs. Start the bike and rotate the head of the Screw/Bolt/Knerled adjuster one way until the idle revschange, if the speed decreases, turn it the other way until the idle RPM is where you want it.

How do you adjust the high speed mixture screw? I have a Ryobi RLH1100a MK III 31cc line trimmer, and after changing the fuel lines, it will start but not idle more than about 3 - 5 seconds before it...

Hi montex124, I will try to help. In the past few years carb makers have been making changes. Some carbs have no adjustment at all, the ports are all fixed inside the carb. Other carbs have only the idle speed mixture screw that can be adjusted, like yours seems to have. Is this screw you mention at the top and completely outside of the carb to adjust the throttle? If it is it's probably the idle speed screw which can be adjusted to any idle speed you want and has nothing to do with the air fuel mixture but If it is right next to the idle mixture screw, it might be the high speed mixture screw but is capped so it can't be adjusted. The low and high speed mixture screws should be marked next to each screw H and L.
The 1 1/2 turns suggested is sometimes just right but other times has to be adjusted, so you can try adjusting it to get your idle but maybe adjust the idle speed screw first to get a higher RPM so it doesn't stall on you. Like I said earlier it just adjusts the throttle, and is like when you are using it, and giving it gas as they say. I hope this helps just a bit. Regards and good luck. Get back to me if you need more help or just let me know how you did. Denis.

Homelite chainsaw model 4620c will not idle unless it is in the half choke position

If the jet screws have slot heads, set 'L' CCW about 1/2 turn more or less. If proper, the engine should idle fairly well, yet allow the engine to 'follow the throttle'. If the jet screws have 'D' heads, you will need to either make a 'D' head screwdriver, or take the saw to a service dealer for adjustment. If the chain is trying to turn after the above adjustment, set the idle speed screw CCW until the chain stops trying to turn. Hope this helps!
