full choke on , push petrol bubble 5 times then pull starter cord., with luck it will kick in to life after a 20/30 secs put on half choke , run again for 30 secs the no ckoke.
The main problem with Ryobi products is that they flood very very easly. So the more time you try and pump petrol into the carb the more it will flood . If that happenes then choke off and switch off and then just pull starter cord for about 30 secs then switch on and it could start if not prime it again as above good luck
I have a flymo 430 petrol strimmer and cannot start it. ive cleaned the filter, put in new plug it went first time and then stopped and wont start again the plug seems to get wet all the time any ideas
Start procedure, switch the ignition switch on, press the primer bulb as many times as it takes to 3/4 fill the bulb, put the choke to the full position,hold the throttle trigger open, crank the engine until it fires once, move the choke to the centre position, crank the engine until it fires up and runs, once warm move the choke to the open position.
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.
When I first got my brand new RYOBI LIne Trimmer the *** thing just would not start. I was following the exact guidelines in the maual. First thing is, ensure you get right is fresh fuel correctly mixed accurately with 2-stroke oil. Some machines are more temperamental about the mix. 2. Set choke to COLD, press bulb 8 times (once you see fuel enteing the clear bubble reservoir) 3. Switch on power. It's amazing how often I've pulled the cord with that red button off. Dont think you cant do it to. 4. Pull the cord gently until you feel resistance. Let it gently recoil, then in one non-aggressive move, holding down the unit with your other hand, pull it out at constant speed. Do not yank! If (or rather when) it doesnt start, pull the accelerator trigger a couple of times only, and repeat procedure "4". Don't press bulb again too often or use the trigger too early or you will flood the engine. When I couldnt get my strimmer to start at all, I got this advice from an online engineer, it fired up *first pull*.
If it's not starting after a winter rest, did you store it empty of fuel because that is always wise. Discard old petrol mix and start with new. Hope that has helped.
Hi
You may have tried this already, Apologies if you have.
I have had the same 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....this solved it for me
