Question: Carb Primer Assembly
does anybody know if there is a part number or availability of the rubber check valve inside/ under the the primer bulb at the top of the carb?
Reply: Carb Primer Assembly
The little marroon or orange check valves made by Walbro will fit these carbs. They have them on Ebay. Search under Walbro Check Valve. They fit and they work.

Your best bet is to take you tool to a shop to have it tuned. I say this for a couple of reasons.
First, The tools for adjustment are not meant for sale to the public. They are only meant for techs trained to tune carburetors to the latest EPA guidelines. In fact there are hefty fines for what the EPA considers "tampering" with a carb. Some manufactures are more careful than others about making sure that only trained techs have these tools.
Second, It is very easy to permanently damage the engine if you are not sure how to tune the carb. Modern engines are built to such tight tolerances and current mix ratios use so little oil that it only takes a few seconds of running the engine too lean for damage to begin. Here in our shop I always use a tachometer to tune an engine so I can be sure that I don't damage the engine.
I hope this helps,
I have a Ryobi 30544 trimmer. It has hardly been used. It starts on full choke but will not run when you take it off full choke. It will not even run at half choke. I took apart the carb., it looks clean. I drained the fuel tank and assured that there is a 50-1 mix. Any ideas?
I have the same exact issue. Starts on full choke, but half-choke or run and it conks out after a couple of seconds.
What I found was the fuel filter separated from the fuel line inside the gas tank, allowing too much fuel when you opened the throttle. The fuel line basically disintegrated on me.
If that isn't the issue, try adjusting the carb mixture to allow a leaner mix (there are a couple of adjustment screws under a plastic cap on the carb).
If you get it fixed post a reply. Good luck.
Hi bill, You need to use a star bit screwdriver. Insert it in the hole in the tip of the drum. It unscrews counterclockwise. The motor will turn, so you need to stick a screwdriver into the air vent to stop it from turning. The star bit size is the same as you used to get shaft off of the motor. I hope this helps.
2 year old Ryobi RY30544 grass trimmer. Can't get it to idle right. have to choke it to keep it running. Had it apart. Fuel pick up is okay. fuel is ok. Dissassembled carb, looks ok. Tried adjusting choke throttle screw. just can't get it to idle. When I hit the throttle, it dies. almost as if the fuel was shut off.
Hey there Paul! Its been my experience with most of these carburetors that the diaphragm and gaskets inside of the carburetor wares out over time causing an air leak which in turn makes it hard for the carburetor to suck gas out of the tank. Even though you took it apart and I am sure the gaskets looked intact they are probably very brittle and not sealing correctly anymore. Unfortunately there is no rebuild kit for this particular carburetor but you can pick up a new one on www.ereplacementparts.com part number 308054007 and that should solve your problem!
hope this helps
Question: Choke Dial Cover
When I loosened the hex nut holding on the Choke Dial Cover, the entire rod (that the hex nut screwed onto) came out. When I try to push it back in ... it runs into something and will not go in all the way. Don't know what it is that is in the way.
What should I do?
Reply: Choke Dial Cover
It sounds to me like one of the parts that the double sided bolt fits through is out of alignment with the others. Buy loosening the other mounting bolt (Item #B43) you should be able to manipulate the carb and gaskets enough so you can thread the bolt back through the assembly.
Hope this helps!

Review: Ryobi - RY30544 Not Worth The Mo...
I just wanted to comment on the trimmer I purchased about 2 years ago..... I rarely use this product, and have had several issues with it. They seem to be common, because the comments I am seeing here, are all the issues I have had.... 1) Keeping it running at the half choke or no coke setting....2)I have already had to have the pulley system repaired.. and now the plastic thumb bubble is shot, and it looks like I will have to buy a whole new carburetor just for that part... it is not worth it... I will go and buy a different brand trimmer, hopefully with better results... I am, to say the least, disappointed.
Review: Ryobi - RY30544 U Will Regret Ry...
This is the second Ryobi string trimmer that I have purchased. Basic fact with Ryobi: They suck!! They will work good for the first year and after that they will fail.. It seems that if they are put through any real work, it will be a matter of time before they fail. My advice: Spend the extra money and purchase a Stihl, Echo, or Husqvarna. My father has recently gave me his 20 year old Husqvarna and it still runs perfect. It still starts after the second pull every time and has never had anything ever replaced on it except maybe the spark plug and air filter. I've had to swap the carburetor (which did not have an air filter) and gas cap on this last Ryobi just to keep it running. You get what you pay for...
Review: Ryobi - RY30544
PROs:- Works with older Ryobi interchangeable componentsCONs:- Plastic Thumb Bubble deteriorates overtime causing gas leaks and overheating possibly due to oxygen mix from the leaking Bubble- Getting the oil mix right can be a pain at times- Some 2 cycle oil types do not work with it at all
