    What is it doing that makes you think the shaft is causing a problem? Is it stalling only when you apply the throttle? Is it stalling only when you hit high grass?

Usually this is a fuel supply problem. It can be caused by a cracked fuel line, debris in the fuel tank of in the tank to carb fuel connection. If you have a primer bulb a pin hole in the primer bulb or (if so equipped) the line that goes to the primer bulb it will do the same thing. Small air leaks will cause the trimmer to run fine at idle but anytime you demand more speed it just will not speed up or it will stall. Additionally the diaphragm in the carb can also have a small hole or tear in it. (Located under the 4 small screw plate on the carb)

A problem in the shaft is rare unless the shaft itself breaks or the internal flexible drive shaft has a partial break and the spring material is unwinding. If this is the case the flexible drive shaft will have to be replaced. It requires removal of the engine from the curved shaft assy to replace. Once the engine is removed the shaft is supposed to just pull out. WHen installing a new shaft you must make sure the 4 sided drive spline drops into the string head or you an not install the engine correctly. The same goes for the engine to shaft mating area. Align the 4 sided spline.

Ryobi CS30 - Stalls out?


Dirt or varnish in fuel filter or carburator. Change filter if there is one.

Flush out the carb with a varnish remover.

Open high speed needle valve 1/8 turn farther, then turn in while running until it just smooths out.

When you rebuilt the carb did you remove and replace the welch plugs. If you did not, then that is probably where your problem is. Debris, varnish and corrosion can build up under the welch plugs and the unit will not pass fuel.

Ryobi CS30 straight shaft. I can not get the string head off to replace the line.


There should be a half sphere shaped object over the spool of string. Twist off in a counter clockwise motion and the spool will come off so that you can replace the line.

Have a Ryobi CS30 Weedeater, will not start, it is about a year old, did not see a spark, just bought new plug.


If you still don't have a spark with the new plug, then you may have a kill switch wire grounding the motor, keeping it from starting. If it's not that, then you have a bad ignition module (coil).

Good fix, mrfixit-jerr! Also, if you remove the rear cover (4 screws) you can stabilize the crankshaft by inserting a screwdriver between the lobe of the shaft and the counterweight.
