Question about Ryobi Three Trimmer Combo

1 Answer

I have a Ryobi SS30 string trimmer with the attatchments. It has never run well since purchased several years ago. At best it will start and I have to run it in the 2nd choke position and hold the trigger just right. At worst it will not start. The gas has the mix, is old but has stabilizer. This is the same gas that works just fine in my mower (w/o the mix). I use for my homne on average 1 or so hours a month

One thing that I have found about 2 cycle engines is that to leave fuel in them over the winter months is asking for trouble, even if they have stabil in them. The reason for this is the alcohol that the government mandates for all gasoline. That alcohol is very hydroscopic and sucks water ito the mixture creating a goo that blocks the needle valve in the carburator, as well as seals the little flapper valves that allow fuel flow. it also blocks the strainer in the tankblocking fuel flow. You can first try this. Remove all of the fuel from the tank. take the top off of the carb and spray a generous amount of carb cleaner down in the top of the carb. replace the top of the carb. Refill the tank with a new mixture of oil and gas (don't use gas that has sat longer than 3 months.) Add a little bit of SeaFoam or any other additive to the mixture. Start/Try and run the machine untill all the fuel has burned off in the machine. refillagain and see if it did any good. If not then you may have to clean the carb and replace the flappers in the carb, as well as fish the strainer out of the tank and clean it. That alcohol sure causes a mess. When you store the machine for the winter, burn off all of the fuel and let the machine be empty for the winter.

Fuel mixture ratio for Ryobi SS300 weed eater

Are you sure about the model number? I see several 30CC engine string trimmers by Ryobi. Two are the Ryobi RY30040B (SS30) and a RY30544 (SS30).

For both of these models, mix a high quality 2-cycle engine oil at 2.6 oz. per gallon of gasoline to pour into the gas tank. This ratio is used in several other Ryobi string trimmer models. Many Ryobi product manuals are available here: . Most Ryobi gas powered and 40V battery-powered tools will have a model number that starts with RY. The 18 V battery powered models often start with a P.

I hope this helps. If you add a comment with the actual model number, I may be able to provide more information.

Engine runs but no power to the head

It could be simple. Sounds like the drive cable came loose or broke. You could get an estimate from a repair shop -- probably not terribly expensive.
