Ryobi trimmer head slow spin

Sup guys,
My neighbor threw out Ryobi BC30 grass trimmer. I ended up checking it out and it needed new gas tank and starter. After replacing those two parts i managed to get the engine running. Now i discovered that when i give it a gas the head spins very slow almost at max of the gas. I can hear the engine running at higher RPMs as i give it gas, but the head just starts moving and then when it touches grass it stops as if there is no power from engine going to the drive shaft.

So first thing that comes to mind is clutch, but are there any other possible causes that could be issues here? What about internals of the shaft? I did not have the time to troubleshoot today but i will look at it tomorrow. Any help you can shed is much appreciated.

The engine runs well, i just need to find ways to get it to transfer that power to trimmer head.

Thanks for your help

If you flip the string holder with your finger when it's not attached to the powerhead, does it spin easily and freely? If not, take the whole string head apart and make sure there isn't a lot of grass and brush jammed in underneath the string holder causing a lot of friction. And check that the grease in the angle drive at the end of the shaft hasn't all dried up (if it's not permanently sealed...some of them are).

And make sure you are getting the square socket and the square end of the spring shaft mated fully by twisting the shafts back and forth as you mate the head with the power unit. The shaft is springy and it's possible for them to not mate properly.

It's a super cheaply made trimmer, not worth spending a dime on for parts.

This could be said for so many posts/threads on this forum...however, it is not helpful nor constructive IMO.

Most likely is the shaft cable has worn on one or both ends. Could be a clutch also.

Thanks guys for the help, ill look into it.

As far as the cheap trimmer for me half the fun is tinkering and getting it to work.

You can also put that engine on another shaft if you come across another one.

The gear head might be stripped. I had a Husqvarna do that to me ~!~!

Often the shaft has slid out away from the engine and the cable disengages from the clutch. Many times you can loosen the clamp and slip the shaft back up to the engine to get itworking right.

The comment about it being cheap and worthless is not appropriate, especially in a forum about doing it yourself. You can throw your weedeater away and buy anohter $100 one away every time a primer bulb breaks, that's your business and waste of money...but some of us prefer to keep the stuff out of the landfills and make it work for us, learning a little along the way.

Slow Spin Head

Nine times out of ten, the shafts break on the Ryobi equipment. My experience with them is they installed a strong running engine and the weakest link is the shaft. I've worked on dozens of them and most are diagnosed with broken shafts. Fairly priced shafts for the do it yourselfer but don't install a blade type head to it.....it will break repeatedly when you bounce it off your landscape rocks, etc....

Thanks for all the help guys. I wanted to give you an update. After my initial repairs I did not properly attach shaft to engines which was basically not able to rotate shaft properly. After I reconnecting the shaft back to engines and making sure that it connects properly, I was able to get the trimmer to spin the head at fast speed. 30$ out of my packet and I got a working trimmer and knowledge how these little guys work.

Thank you all for your help!
