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...

Sounds like you have dirt/debris in your carburetor jets,fuel passages or a diaphgram that is becoming non-flexible.
NOTE: Before you dissemble the carburetor:
Make sure you mark each piece with a awl, or some kind of instrument that will make an alignment scratch before you dissemble the carburetor into separate pieces.
That way you will know which way it goes back together when you reassemble it.
Be sure to check your fuel tank for water and dirt/debris, if there is water/debris then you need to clean your tank.
Also check you fuel line condition after a while they will degrade and need replacment.
Make sure you are getting spark at the spark plug, to do this:
Remove your spark plug and check to be sure you are getting fire at the spark plug.
You do this by grounding the plug on the head of the engine and pulling the crank rope, if you are getting spark then:
Check/Clean/Replace your fuel filter if you have one, normally they are located in the fuel tank of weedeaters.
When you remove your fuel lines from the carburetor be sure to make a drawing to how the lines are connected to the carburetor.
Normally the big line will be the line the fuel filter is connected to inside of the tank.The smaller of the two lines is the return to the fuel tank from the carburetor after it is pumped thru the carburetor by the primer bulb.
Also make sure you are using fresh fuel...and oil mix if your using a two cycle mower or weedeater with the oil to the right mixture and not too much oil as it can cause hard starting.
If the mower/weedeater is over a couple of years old, then I recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.
Sounds like you will need to clean the carburetor or replace your carburetor internal rubber parts like the diaphgram and O rings.
I recommend that you use a laquer thinner type cleaner to clean and dissolve the laquer build-up in the float and needle jet passages.
Be sure to remove all plastic and rubber parts before using the laquer thinner because it can dissolve the plastic parts and render them unuseable.
Be sure to use compressed air to blow out all the fuel and air passages.
Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.
Sometimes you can get by with priming the carburetor or using starting fluid and letting it run a few times like that and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.
Keep in mind that the float (if you have one) for the carburetor must be level when you go to reassemble the carburetor or follow the instructions you get with the carburetor kit.
When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.
But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.
Be sure to mark the turns down on a piece of paper.
That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their original position before you started.
Once you have your carburetor rebuilt that should solve your problem.
