i have a new Riobi RBC30SBC stimmer that wont start
it has been back to the manufacturers they have replaced it but it still will not start.

I had the same problem starting a Ryobi strimmer.Turned out to be a defective spark plug cap. Would start if you applied pressure on the top of the cap but immediately cut out when I removed my hand. I replaced the cap and it now starts and runs fine.

These small two strokes really need their own starting technique.....
Press the primer bulb a few times (If it has one)
Put the choke on full
Apply full throttle
Pull the recoil starter very briskly until the engine pops
Take the choke off, but keep full throttle
Pull the starter briskly again and you're away!
