Put in 4 cyl. oil mix instead of my 2 cyl. accidently , it starts but shuts off in a few seconds , i also notice the spinner gets stuck too it rolls and then stops.

What can i do to fix the problem ,help please . Any advice would be helpful , thanks rich ..
Drain all the gas/oil mix out of the system. Press the red prime bulb several times until there is no fluid in the line. Pull the spark plug and clean it with a soft dry rag. Reassemble and fill tank with 2 cyl/gas mix. Prime it, then pull several times on the start cord. That should work.

A 4-cycle engine requires regular gasoline whereas a 2-cycle engine requires oil to be mixed with the gas.
A 4-cycle engine requires regular gas in the gas tank and engine oil in another tank. Your owners manual will tell you what grade of oil to pour into the oil tank compartment of the weed-eater.
A 2-cycle engine requires regular gas plus a certain amount of 2-in-1 oil mixed with it. The oil that is mixed into the gas container and shaken together to "mix" the gas and oil before pouring into the gas/oil tank helps to lubricate the moving parts of the engine like the piston movement between the piston and the pistons' wall known as the cylinder wall. Also the oil aids in the creation of a tight seal which causes compression to occur that is responsible for optimum operation of the engine itself. It also provides lubrication to the piston rings and reduces friction as the piston rings push against the cylinder wall.
4-cycle engine oil can be purchased at any oil store like Canadian Tire/Sears/Napa Auto Parts. Just ask for oil for your weed-eater and let them know that your engine requires 4-cycle engine oil. I am sure the service clerk will point you in the right direction.
I hope this helps!Have a great day!
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: https://www.ryobitools.com/power-tools/support/manuals . 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.
This may sound like a dumb question, but did you mix the fuel and put it in the machine? If so, you shouldn't have. 4 strokes don't take mixed fuel. You must put the SAE 30 Oil (Not 2 cycle Oil) in a different chamber. Let me know, PLEASE!
There is a special 2-stroke engine oil mix that you can purchase at various stores that have outdoor equipment or you can also find mix at Walmart. There are instructions for proper mixing on the bottle.
Remember not to put 2-stroke mixed fuel in your lawn mower unless it is also 2-stroke (rare). And the converse is also true, do not put your 4-stroke lawn mower fuel in your 2-stroke weed eater.
You did not list which model Ryobi you have, however...
If your Ryobi has a silver or black shaft, then it is an older model and requires a 32:1 fuel mix. In the USA, that is 4 ounces of 2 cycle mix per gallon of gasoline. If your Ryobi has a yellow shaft, then it was made by HCP and uses a 50:1 mix or 2.6 ounces of 2 cycle mix per gallon.
You only need to mix oil with gas when it is a 2 cycle engine. 4 cycle engines run on straight gas. Since you didn't post your model number, here is a site you can hopefully find your owners manual at. Hope this helps. http://odref.com/pdf/Ryobi/
