Questions & Answers

What kind of fuel does this model use, plain gas or gas/oil mix, have lost book, if mix then what amount
Carol for model number RY29550
Hello Carol, thank you for your inquiry! Two-cycle, or two-stroke, engines require you to pre-mix oil in the fuel to lubricate the piston. Without lubrication, the engine will seize. A seized engine is not repairable and makes for a bad day of yard work. To prevent a costly mistake, always mix the specified 50:1 gasoline-to-oil ratio for the Ryobi RY29550 lawn trimmer. I hope this information helps!
I replace the B 16 part used a short time and it got so hot that it melted the cap where it slides over the hex head on B 8 that is driven by the cable. Is that head supposed to be lubricated on the end of the shaft?
Ronny for model number 29550
Hello Ronny, Thank you for the question. I am not showing a lubricant listed or recommend when replacing these parts. I suggest checking to see of the Gear Head, Part Number: 308210009 is getting hot and causing the Housing to melt. The Gear head may need to be replaced. Hope this helps!

Question: Air Filter

Skirsch

Does this cover come with the actual air filter?
WJA
Hello Skirsch,

The part number for the air filter is 518766001 Air Filter Base. The mesh material you see on it acts as the filter. It's not the best filter I have seen, but they have been using this style of filter for years.

-WJA
Question: Wire Harness Switch

frankc67

Is it possible to get the switch only or do I have to buy the complete wire harness ? It appears the start switch comes with the Wire Harness
Part Number: 308315001
I need the electric start switch, color black with 3 pronges for wires.

Thanks
WJA
Hello frankc67,

Unfortunately the manufacture does not sell the switch only for this unit. As you stated the complete 308315001 wire harness will have to be ordered.

-WJA
Question: Carburetor Kits

noonotyes

are there any kits avialable for these carbs 308054013
WJA
Hello noonotyes,

The cost of a carburetor kit would probably come close to the cost of the a new carburetor,part number 308054013. I would guess that is why the manufacture does not offer the kit. One other thing you might want to order the gasket for the carburetor depending on what model you have.

Hope this helps,
-WJA
Question: Handle

spake3

can i just order to yellow arm that operates the run and start button or has anyone got one off an old carb they cld send me
WJA
Hello spake3,

I think the choke lever you need is part number 518824001.

Hope that helps,
-WJA
Question: Air Filter

1024748

Does the Ryobi ES-30 M#RY29550 Trimmer have an air filter in the air box? Mine does not.
WJA
Hello 1024748,

The air filter for the RY29950 Trimmer is part number 518766001. It is located right under the air box cover.

Hope this helps,
-WJA
Question: Eyelets

Jmeitzler

Can i purchase replacement eyelets only or do I need to purchase the entire housing? If so what is the part code for the eyelets?
WJA
Hello Jmeitzler,

Unfortunately the manufacture does not supply the eyelets only for this model. So the housing with eyelets, part number 308827002 would have to be ordered.

Hope this helps,
-WJA
Question: Trimmer Fuel Lines

Ghook73

Can I replace fuel lines that have dissolved after a year use - or do I have to replace the entire fuel tank assembly?
WJA
Hello Ghook73,

Unfortunately the manufacture does not supply the fuel lines for this model, so the complete Fuel Tank Assembly will have to be ordered. On the upside, you do receive a new cap and fuel filter with this also.

Hope this helps,
-WJA
you can replace thr fuel lines,,get them from any local repair shop ..cost about ..$2.50....
Question: Adjusting Carbuator

tom

Is there a special tool for adjusting the carburetor on RYOBI line trimmer model RY29550, or do you have to buy a new carburetor?
Yes there is a special tool for adjusting the carb, your local dealer will have one, not for sale though.
WJA
Hello 624600

EPA Carburetors

Your machine has an "EPA" carburetor. Starting in 1997 The EPA placed requirements on how clean small engines are required to burn. As part of this restriction the carburetors are set at the factory. The carb then either has the adjustment ports capped or they use special adjustment screws so that the carb can only be adjusted by a tech trained in compliance with the EPA directives. The manufacture offers the special carb adjustment tools their authorized repair shops but not to the general public. The manufacture is liable to ensure that the equipment they sell complies with the EPA directive and therefore will typically not offer the adjustment tools for sale to the general public. You can learn more about the EPA emissions requirements for small engines at the following link...

http://www.epa.gov/otaq/consumer/f98025a.pdf

Before you adjust the carburetor you should determine why it needs adjustment first. A carb should only need adjustment when it is new and needs to be adjusted for altitude or after a carburetor rebuild has been performed. If a piece of equipment has been working fine and then starts acting up there will be more repair issues than a simple carb adjustment. The carburetor itself will not simply go out of adjustment. You will want to look at things like a tune up, a clogged carburetor, a plugged exhaust system, ignition problems, etc. Adjusting a carburetor requires some knowledge and experience with small engines. You can easily overheat and seize the engine if you are not familiar with the proper procedures. It is also a good idea to use an engine tachometer to be sure that you make the correct adjustments.

I hope this helps with the repair of your small engine!

I used my dremel tool and cut two slots in the adjustment pins. Now I can use a slotted screwdriver to adjust the high-speed and low-speed mixture and it runs great. Needed to be slightly richer.
