there are two ways to install the string..the cool way is without pulling the inner reel off the trimmer..just leave it in place..cut (2) approx.two arms length (thats spreading your arms out like airplane wings) of .095 string..now, align the arrow of the inner reel (it turns counter clock-wise..the arrow points outward) with the arrow on the outer spool (pointing inward)..holding the spool and reel together so the inner reel doesnt move, push one of the cut strings through the eyehole in the side of the outer spool, and it should come up to the right, through a slot next to a small round hole the diameter of the string..if it doesnt, it just missed the exit (as i call it)..pull out and try again..let about an inch come thru..now take that end of the string and push the line into the little round hole until it stops, which should be about a little more than 1/8 of an inch..hold it in while pulling the excess line outside the spool to keep it in place..now do the same with the other string for the other side..once you have both lines in place, turn the inner reel counter clock-wise to draw in both lines through the eyeholes of the outer spool..you may or may not get all of the line to wind in..not a problem..you will still have enough to do what you need to do..just cut off the rest..one problem you may or may not have that i do most of the tyme is that it gets hard to turn the inner reel..one solution is to bump the top of the 'bump knob' with your fist, then pull both strings at the same tyme, then continue to turn..this method is quicker and easier than the second way of having the inner reel out and trying to wind both lines at the same tyme and trying to place the reel back in the spool..hope this works for you...

Hello. Let me assist you. Since your trimmer runs but stalls at ful throttle it is telling you that there is a fuel problem. Not enough gas is getting through the carbeurator to satisfy the engines needs on full throttle. Most likely the carbeurator is gummed up. A common problem. Let's see if we can un gum it by getting a can or carbeurtor cleaner. Go to any auto parts store and talk to the clerk about your need.

Hold orange spool containing string while twisting the black plastic cap in the center, counterclockwise. This retaining cap is loosely spring loaded, so watch for the spring falling out. Once this locking cap is removed, the spool pulls right off.

The small diameter line out of fuel tank (has filter in-tank on end) connects directly to the side of the carburetor that has the fuel pump....that is the cover without the hole in it. Other larger diameter fuel line out of tank connects to the longer nipple on the external purge/primer bulb. The bulb "pulls" fresh fuel from the fuel tank to the carb and then out of the carb to itself, where it then "pushes" any air/old fuel back into the fuel tank. The remaining larger diameter fuel line in this setup goes from the metering chamber (has cover with writing on it and a vent-hole) side of the carburetor to the smaller nipple on the purge/primer bulb. Again, on the primer bulb, the longer nipple has a line going directly from it to the tank. This is the return line. The shorter nipple on the bub has a line from it going to the metering chamber side of the carb. If the purge/primer bulb is on top of the carb...small line from carb body to small hole in tank with filter. The larger diameter line goes from the bulb on the fuel pump side of the carb to the larger hole in the fuel tank where sometimes the line is held in place with a nylon nipple connector that keeps the line from pulling out of the tank. Otherwise, the line should enter the tank for about 1/2" or so.
