Ryobi makes a neet little fuel line kit for these , and its inexpensive too , it contains a new fuel filter (and tool for installing it) a new primer bulb (change it anyway) and enough of two different fuel line to reach your trimmer's carb , I stock a few of these here and you can buy ne from any roybi dealer , the only tool you need besides your fingers are a pair of scissors and a Phillips screwdriver for taking off the air cleaner to gain access to lines
directions are included on back of package
I have a Ryobi Model RY28040 straight shaft line trimmer. In my case I replaced the complete String Head Assembly that includes the String Head Housing, Spring, and Spool and the string still did not advance. I then discovered that the bolt in the Spool Retainer cap (the red cap that attaches the spool to the shaft) was fused and not moving. The bolt needs to be loose inside the cap in order to allow the spool to move in and out by the spring. I loosened the bolt and fastened the spool back onto the shaft. Fired it up and bumped it a few times and the line began to advance. Turns out I probably only needed to replace the Spool Retainer rather than the String Head Assembly.
Ryobi told me the unit can't have the s430 trimmer bottom end raised higher than the engine at any time, or it will leak. Apparently they released a product to compete with other companies for cheap 4 cycle trimmers without much care for the end user.
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.
To install string in the Ryobi you do not have to disassemble anything: Line up the two arrows on the inner and outer reel, remove any excess string, cut two
pieces of string about 10 feet, feed line in the side holes, secure
line in hole where it comes out the bottom (it only takes about 1/4in.
to do so), pull strings tight, then turn the inner reel counter clockwise to wind it. If
it sticks a little just pull line a little.
To remove the inner spool in order to remove line that has broken
inside, to clean the mechanism, or to perform other maintenance, grasp
the outer reel and unscrew the bump knob counter-clockwise. Mine is
often very tight and requires pliers to get enough leverage. While you
are in there, clean the inner reel and the inside of the outer reel to
improve feed performance. The shaft rarely needs cleaning. Do not
lubricate. After re-installing the reel, add string (0.080") as
described above.
