Every year people get mad at the weed eater and toss it in the trash and go buy a new one. I’ve done it two or three times myself before learning the most common problem. If you see them in the trash pick them up and take them home! If yours don’t start 99% of the time it is for the same reason, air is getting sucked into the carburetor. The cause is almost always the same, you failed to drain the tank and run the engine until it was empty of gas. What happens is the gas melts the plastic hoses that bring gas from the tank and to the carburetor. You can do the repair in 10 minutes for under $3.00. Go to a rental center and buy a new fuel filter and a foot of hose. Bring the weed eater with you so you can compare size of the hose. While there buy a new spark plug too. The trick is getting the hose through the small hole in the bottom of the tank. Cut a foot long piece of thin coat hanger wire and stick it in the hose, taper the hose with a razor blade and carefully place a piece of cellophane tape over the taper so it doesn’t slip out when pulled through the hole. Remove the gas fill cap and remove old filter and hose, then direct the wire through the hole and seconds later you have a like new weed eater that usually cranks the first or second try.

Good thinking... We save our seeds from fruit we eat, instead of buying new seeds each spring, and it's an excellent and free way to replenish the garden. It's small but it does wonders!
