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?

Where do i buy a carb adjustment tool for a Ryobi RY30544 Trimmer?

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'm trying to replace the pull string on my Ryobi trimmer, but I can't get the drum & connection rod off.

I can not get the spool to turn to where the slots will line up for removal. The red removal nut will not unscrew, it just turns round & round. The string is broke off in the spool so I need to remove the spool to re-thread it.

How do you remove the drum and connector?

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.

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?

They seem to be common 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 I am, to say the least, disappointed. krzycho

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.

Great power tool I like my power tool.

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...

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
