Question: Leaking Gas

Daved

I've got a trimmer that I've had since '06. Up until this year it has run very well. It still starts and runs ok but it leaks all the gas out of the tank when I hang it up. I pulled the tank and all the hoses look good. No visible splits or cracks. I'm going to replace the tank now that I have it off, but what else might need replacement while I have it tore down?
Hello Daved It sounds like you are in need of NEW fuel lines. They deteriorate over time and shrink. New ones are needed as they are fraction of an inch LARGER than the holes they go thru in the fuel tank and they SEAL if from leakage. Get a new fuel filter also. It is installed inside the fuel tank at the end of the fuel line that feeds the fuel to the carburetor. The other line is shorter and is the return fuel line.
Question: Won't Start New Parts Installed

charley992002

Hey there, I have a Ryobi SS30 straight shaft trimmer. I replaced the fuel tank because it was leaking along with the fuel lines and cap, the spark plug, ignition coil and air filter I bought from link removed. I got a new carburetor from the other guys cause ereplacement didn't have them. The trimmer has always been hard to start, so I start with the fuel tank and plug. Got mad and broke the plug wire, so I get a new coil. Still no start, so I get a new carb. What is wrong??????? HELP
Hi Charley If your machine is older, it may have compression issues. There may be an excess buildup of carbon inside the engine. You could possibly have a stuck piston ring(s), which lowers compression making starting difficult.
You may also have a clogged spark arrestor screen inside the muffler, which chokes the machine. Check that and also check to see if the muffler is clogged. If you remove the muffler, you can check for a stuck or carboned up piston ring through the exhaust port. Use a good strong light and a small screwdriver and see if you can wiggle the ring at all once you have it in position to check it.
Thank you will try that this afternoon.
Charley, Did you set the air-gap properly on your new coil. It should be around .008"-.010" from the coil leg to the flywheel magnet...about the same thickness as a standard business card. A card works great as a gauge tool by the way!
Muffler and arrester screen good. Compression at 90 psi, check spark with spark tester, getting spark. Pulled spark plug laid over the hole, gave a couple of three pulls and had fire shoot out the hole. Pulled the coil out to check the gap between magnets on flywheel and coil, do you know the gap size. A video said about the thickness of a business card WTF does that mean? Could the gap be that critical that the spark is not hot enough? Feel like an old fool chasing a young girl and still not getting satisfaction.
Sorry your post was not visible when I replied earlier. OK so business card or feeler gauge, I have an idea of the correct gap. The magnets on the magneto/flywheel were very dirty, so cleaned them off with a rag and some aerosol cleaner. Will assemble the damn thing later this evening. Hell I own a motorcycle repair shop and this POS is making me looney. I put the Pivotrim head on it a couple of years ago, can do the entire yard without the string breaking or getting balled up inside the bump spool. That is why I want to salvage this thing, when it runs it does the job. The born on date was 08-04, August 2004 maybe, I got this thing used a long time ago, the sticker since peel off that had the exact model on it. I understand the s shaped clutch plates are no longer available. maybe somone on eBay has some knock-offs somewhere.
Question: Replacing String

mickgard

I have an ss30 with the "easy" replace string head. I have replaced string before with no problem bur now the string will not feed through the head. I have it lined up properly but cannot get it to feed through. I went to buy a new head but the local home depot does not have the same replacement head and I don't see one on this site. Suggestions?
WJA
Hello mickgard,

Ryobi has two different complete stringheads for the SS30 one is the 000998265 and the other is the UP04650A. I don't see that we carry the Easy Replacement Stringhead by Ryobi. The one we do provide is the Shindaiwa 78890-30000 SpeedFeed Head. Which is loaded the same way as the head that you are speaking of.

Hope this helps,
-WJA
If you have the same easy feed head I have where you just puss a button and feed some line through . I had to take mine apart because the line got burs on it inside !
Question: Ryobi Ss30

georgie007

my ryobi starts fine, but will not stay on steadily. If I leave it on no. 2, it will work. Once I go to the third lever, it stops.
I don't have a filter. Could that cause the trimmer to not perform as it should.
Also, I am missing the bumer head knob, bumper. I just have the spool and a red nut securing it to the assembly.
WJA
Hello georgie007,

Without the 98760 filter. Your carburetor probably has debris in it and may be clogging some of the fuel pathways in the carburetor. Here is a link to an article and video on how to properly clean your carb. How to Clean a 2 Cycle Engine Carburetor. For the other parts you need, take a look the parts diagram and determine what parts you need.

Hope this helps,

Question: Clutch And Drum Assy

1118880

My trimmer head stopped turning. The upper and lower shaft assy are good(cable not broken) I've taken the drum and clutch off. The clutch is the old type with a spring holding the 3 sections together. One of my questions is, is the drum suppose to have some type of lining on the inside for the clutch to make contact with and turn the cable? Or is it metal to metal? The inside of the drum has a lip on the side closest to the starter, there were no pieces of any material, but it seems something was there, it was like a black caked up substance. Thanks in advance for any assistance. Rjmartin41
WJA
Hello Rjmartin41,

The clutch drum part number, 308177001 has no lining on the inside for the 300960002 to make contact with. As you said it is just metal to metal, and after a while, most likely the clutch drum will wear out, and need replacement.

Question: Primer Bulb

pepq105

Doesn't someone make a replacement Primer Bulb for this thing?
The part is removeable but there is no way I'm buying a new carb.
WJA
Hello 1144663,

Try ordering part number, 01183 air purge bulb. Item number 28 on the parts diagram.

-WJA
Item #28 on the diagram is a screw?
WJA
Hello pepq105,

I apologize, the part number 01183 is on page 2, item number 28 on the parts diagram for the model number Ryobi SS30 (RY30043) and on Ryobi SS30 (RY30040) . For the rest of the models if you look at part number 561635001 primer. It should work for those carburetors

-WJA
YES!!!! Home Depot has a Ryobi replacement fuel line kit which also has the primer bulb within. I purchased on this morning for $6 and change.

The part is removeable but there is no way I'm buying a new carb."
Question: None

I have a SS30 Ryobi weedeater. The carburetor was disassembled by someone else for cleaning. I have 2 gaskets that obviously go together. One is regular gasket material and the other one is a real thin film gasket.

I need to know which one goes on the side next to the main carburetor body and which one goes nearest the small part where the priming bulb is mounted? The parts breakdown has no detail on this installation.

Thanks in advance.

Hello Eddie,

The thinnest of the two is placed on the main carburetor body. Make sure the holes all match up correctly. And the thicker of the two is placed closer to the primer bulb.

Hope this helps,

This is exactly what I needed, Thank You for taking time to respond.

Question: Won't Start Without Fuel Poured ...

I have replaced the fuel line as I thought the fuel wasn't getting to the carb, also cleaned the jets. Now I notice that when I press the primer bulb I can see a bubble of air that I've never noticed before. Any ideas?
Thanks

Question: Carb Rebuild Kit

afinkoo7

Does ryobi or parts replacement make a carb rebuild kit?

Hello afinkoo7,

It looks like the manufacture does not furnish a carb kit for this model. You might want to remove and replace the gaskets that are available. And then clean the carb. Here is an article and video on carburetor care and cleaning. How to clean a two cycle engine carburetor.

Hope this helps,
