Adjustment of the gas air mixture on a Ryobi ss30 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: 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.

Idle air mixture screw needs adusting

This is a tell tale sign of a lean fuel mixture. By choking the unit you are manually creating a richer fuel mixture. I would purchase a compression tester from a local parts store and check compression. If that's ok, I'm willing to bet the problem is still carb related. Two stroke carbs are tricky to clean because of high/low ports that are one way and sometimes impossible to clean. Did you remove high and low needles when cleaning carb? Another trick is to mix seafoam with your gas, then mix two cycle oil to proper ratio. Use 2 ounces seafoam to one gallon of gas, then mix two cycle oil to proper mix. Hope this helps! Good luck and happy wrenching!

I work with weed eaters and mowers. Weed eater fuel ratio is normally a 40:1 ratio. That usually all weed eaters fuel ratio.

check air filter and spark plug if good carb adjustment is needed or carb may be loose. could be bad fuel water in gas will cause this

You probably need a slight carburetor adjustment. Try to turn the L mixture screw (the one near the bottom of the carburetor on the air filter side, closest to the engine) 1/8 to 1/4 of a turn counterclockwise. These mixture adjustment screws ( L and H) have odd heads on them and conventional tools won't turn them. I use an automotive type plastic wire connector (around 22 gauge) with a ring terminal end which I can hold. Tap the plastic end of the wire terminal connector onto the head of the screw with a small hammer and this will enable you to adjust the L screw. This adjustment will increase you high speed side and possibly allow it to run off choke in a regular manner.

If it runs with the choke closed then it's not getting enough gas. Check the gas filter on the end of the gas line in the gas tank. Remove the gas cap and using a piece of wire with a hook on the end, reach in the tank and pull the gas line out through the opening. Check the filter on the end of it. You could also have a burst-ed diaphragm in the carburetor. This sucks the gas from the tank to the carb. If that's the case a new weed eater may be in order unless you can find someone with the parts to repair it. Also check the gas lines for leaks or breaks, 2 of them.

you need to replace fuel filter inside the fuel tank . fish it out with and empty tank using a coat hanger and a small hood bent on the end.filters are around $9.00

The spool retainer nut loosens when you turn it clockwise . The opposite of " normal ".
