Question about Ryobi Garden

My Ryobi weedeater engine keeps stalling out.

I was using my Ryobi one day and I flipped it upside down while it was running. It immediately stalled out and now I am unable to rev it up fully because it continues to stall out completely. What is wrong?

    I can crank my ryobi weedeater in choke and it will start. Then I put

    it on run and crank. It will start, then stop after a short time. Than it

    gets harder an harder to start. I have cleaned the carbeurator, checked

    the muffler for clogging. I replaced the fuel tank, because it was leaking.

    I will not run more than 15 or 20 seconds. I found a lot of dirt in the

    carb and blew out all ports with my compressor. Is ryobi mad a me

    or just dying?

    I have a Ryobi weedeater and it will start when I have the choke on but then when I try to take the choke off it stalls out. I have checked the muffler and everything else. What could this be?

    I have adjusted the H screw after setting the L screw to the correct idle setting. The machine only will run at idle. I've replaced the fuel filter and the lines. I flushed the careburetor with cleaner. What else is there to try?

  • YardDuck May 15, 2009

    It worked! However I turned the (left) plastic screw, counter-clockwise, and I was able to flip the choke to "C"....now it runs like a champ.

    Thanks so much for the advise!

    3 things that shut down ryobis.



    1.Fuel hose split/perished and or fuel filter broken off in tank,,simple fix.



    2. blocked exhaust by insects poke somthing in hole to clear out.



    3. carby diaphrams hard/ britle causing pump not to work and or not metering fuel..



    becarefull using compressed air on the carby too much pressure will destroy the check valve in body.



    As a starting point high and low mix screws set to 1 to 1.1/4 turn from just seated...

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!

My weedeater started to kill while operating. The idle and run were fine. It kills like I hit the stop switch. I pull once and it starts right up then kills 30 seconds later. Any ideas on this.

My CS30 that I just bought worked fine the first time I used it. It sat in the shed for maybe 2 weeks and when I tried to start it I had the same problems as nimmote wrote about. I wanted to use his suggestion to adjust the H and L jets on the carb, but didn't want to dremel out the guard and screws (in case I needed to return it). I tried several things to try and fit around those sloted adjustment screws and found that a 3/8" copper Watts "All-Tube" Nut Sleeve & Insert (that can be found in any hardware stores plumbing section) was the best. You simply pull out the insert and tap it onto one of the screws. I first tapped it on the H screw using a small hammer and keep in mind that the first time you have to use enough force to mold the copper mold around the screw, but once it is on there it is easily removed and placed on the L screw. Just look inside the insert and you can see a notch where it has been recessed around the screw slot. You line that notch up with the slot on the other screw and it slides on by hand. You can then use needle nose pliers to adjust either screw as nimmote described.
Now my CS30 runs like a champ!
In my case I had to turn the L screw about 1/2 turn CW to reduce air flow at idle and the H screw a 1/4 turn CCW to let in more fuel at full throttle. My understanding is the L screw is a needle valve that controls how much air is allowed in the carb and the H screw is a needle valve that controls how much fuel is allowed in the carb. Anyways hope this helps someone, it is absurd that they are not sloted screws that the end user is allowed to adjust...

    Removed both screws L and H and use a hack saw to cut a slot for a slotted srew driver. Put the screws back in all the way and back off counter clock wise one and half turn, start it up till warm and make you adjustments. Good luck

Thanks for the advice, it worked. I had the identicle problem as describes (would start, but wouldn't idle and as soon as I gave it gas or moved into the B or C position it would die out)...The one thing I did differently was that I was able to slightly turn the L screw (white/clear casing) a half turn counter clockwise without removing it (there is a slot that a flat head will work on without removing the white casing and the screw will actually turn) and then I used a pair of plyers to pull off the red casing (H screw) completely as there is no way to turn the screw with a screwdriver with the casing on. Once I pulled the red casing off, I used a small flat head to also turn the H screw a half turn counter clockwise. Started it up and it idles well and runs well. Thanks for the advice. I would have had no idea otherwise.

You can thank the EPA for all of these mixture-limiting BS contrivances.
The first thing I do on any engine that comes in for repair is to remove all of the limiters, then the mixtures can be adjusted correctly, according to the conditions needed for proper operation, and not conditions mandated by the EPA.

Before you start touching the plastic covers on the fuel mixture screws make sure they are factory set and then move on to other fixes. These plastic set screws should be set that they touch one another flat faced. there is a cam type lobe on these plastic covers. Use needle nose pliers to turn them slightly towards each other (perpendicular) if you don't have the correct screwdriver.

    Search eBay for part number 530035560
    That would be the Splined Carb Tool you need.
    You can get one shipped for less than ten bucks, even an actual OEM part (not after market).

My idle was set too high. I had all the same problems you all describe, turned the idle down until it nearly died then turned it up a quarter turn. Runs perfect and most of the time will start without choking it.

You can get the tool on ebay. There are several types. Most Ryobi's use the "pac-man" named such because of the shape of the head.

I have a cs30 ryobi weedeater and something in the shaft is causing the weedeater to either stall out or completely shut off, how can i fix this problem?


Usually this is a fuel supply problem. It can be caused by a cracked fuel line, debris in the fuel tank of in the tank to carb fuel connection. If you have a primer bulb a pin hole in the primer bulb or (if so equipped) the line that goes to the primer bulb it will do the same thing. Small air leaks will cause the trimmer to run fine at idle but anytime you demand more speed it just will not speed up or it will stall. Additionally the diaphragm in the carb can also have a small hole or tear in it. (Located under the 4 small screw plate on the carb)

A problem in the shaft is rare unless the shaft itself breaks or the internal flexible drive shaft has a partial break and the spring material is unwinding. If this is the case the flexible drive shaft will have to be replaced. It requires removal of the engine from the curved shaft assy to replace. Once the engine is removed the shaft is supposed to just pull out. WHen installing a new shaft you must make sure the 4 sided drive spline drops into the string head or you an not install the engine correctly. The same goes for the engine to shaft mating area. Align the 4 sided spline.

Thanks for choosing FixYa.

It keeps stalling after only a few minures


Suspect Ignition Coil is failing under heat.
To test this, take the unit outdoors and have a fire extinguisher handy. Start and allow unit to run until it shuts down. Then remove spark plug and test for spark by grounding the outer shell of the plug on the engine's metal surface.

BE SAFE!
Keep your face away from the spark plug hole as you pull the rope to test for spark. Expelled fuel or vapors can ignite via the removed spark plug or any subsequent arc.

If no spark when hot, and good spark when cold, replace ignition coil.
Find your EXACT model number on your unit, then go HERE to lookup the part number of the coil. Call your local reputable repair shop and ask if they have it in stock or can order for you.
Hope this helps.

Ryobi lawn trimmer keeps stalling out. I have


If it is a relatively new unit it should have the carburetor adjusted after the first few hours of use. If it stalls upon accelleration the low speed adjustment on the carb needs to be opened a little bit. If it runs a few minutes and then stalls it could be the high speed jet needs to be opened or the fuel filter is clogged.

Ryobi stalls after starting.


Yep had same problem it would run for about 20-30 sec and then just stall.
solution is the diaphragm on the side of the carby I swapped mine for the same one in my blower and it fixed the stalling problem.
The diaphragm operates the fuel into the carb. loose fuel lines can cause similar problem.

Have a 96 camry 4 cyl auto. After highway driving, the idle becomes rough and wants to stall. The problem eventually goes away after driving a city speeds. Around town, it runs all day just fine. Help ,...


Here is the most common cause of surges and stalls and low idle, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
