Question about Lawn Trimmers & Edgers
Have recently purchased a petrol strimmer - how do I replace the pull start cord.
SOURCE: Strimmer Line
rotate the starter pulley by hand. You should feel the spring getting tight. Once the pulley is slightly tensioned, usually 5-10 turns, release the pulley and let is pull the string onto the pulley. You may have to add some tension to get all the rope to wind on the pulley.

I have had the similar problem & spent a day stripping the unit down
(dismantled & re-assembled the carb, seemed OK fuel reaching & flooding the plug) I unscrewed the spark plug from the body, but left it connected to the lead and found that there was intermittent spark when pulling the cord. and tested it with a continuity meter - no signal/measurement. bought a new spark plug, meter reading showed signal/measurement, now starts every time. It may be that Ryobi has been installing rather cheap nasty plugs. So test the plug first by watching the spark when pulling cord, test with a meter, if no continuity, buy new plug....
Check also that little gauze air filter behind the roto choke is not blocked.
this solved it for me.
Please remember to give me a rating ...ta

You need a long skinny T25 torque driver (sold in a pack at Lowe's with 3 other sizes.)
Take off the 4 screws in the back to reveal the piston. Get a wooden dowel (or a wooden spoon if your wife isn't around) and stick it in to the piston to block it from spinning.
Now take that T25 and stick it in to the front pulley (cone shaped silver item that is preventing the housing from coming off) turn to the left and it should come off.
That should come off to reveal about a 1"x1.5" piece with a spring wrapped around it. That can also turn to the left and come off with an adjustable wrench or pliers.
Once that is off the housing should come away and you'll be able to get at the pull cord after removing 4 more T25 screws.

If your petrol has been sitting in the machine for a long time then yes it is your petrol. Mix a new batch usually you cannot let that sit around for more than 30 days, I always try to use fresh mixes, usually that means making smaller batches unless you use your trimmer quite a bit, most people do not though and that's when problems arise.

A lack of acceleration in these units is most likely a fuel delivery related issue. It may possibly be time for a diaghram kit or carb rebuild kit to be installed in your carburetor. Ethanol in the gas deteriorates the parts that accomplish the acceleration procedure and may need to be replaced as they don't function anymore.
Many other things can affect these little machines as well such as clogged air filters, clogged crank case vent, clogged mufflers/exhaust ports./ spark arrestor screens...but more often than not, your problem is a carburetor issue.
