Possibly dirt in the fuel system. Blow out the line from the carb and make sure there is no dirt in the bottom of the tank.

SOURCE: The weedwacker dies when I squeeze the throttle trigger

You need to clean the carburetor. Remove and disassemble carb. Use a den Tek Brush, (used to clean between teeth), to clean the small portals in carb. Use a carb. cleaner while cleaning. Make sure the small screen in carb. is free of debris. The smallest of paticles can cause the carb. not to run right. Reassemble the carb. and try starting. If there is no change, then you will need to buy a carb. kit for your trimmer. Replace all appropriateparts: gaskets, diaphragm, needle valve, and the small screen.

SOURCE: craftsman 32cc would not idle

If you are certain that you have correcting gaped the plug then the next step is to readjust the low end idle carburetor. If you look you should see two holes in the plastic cover that lead to the flow adjustment screws they may even be out in the open. If they are not labeled H and L (the L is the one you want), check your manual for the correct one. A good place to start is turning the screw all the way in then backing it out 1 1\2 turns. Then check it. If you still have problems do 1\4 turns out. After about one full turn from that you might want to consider taking the carburetor off and removing the float bowl or the bottom for a good cleaning. A sticking float could cause problems with your fuel flow.
Hope this helps.

SOURCE: runs but dies when I squeeze trigger

Sounds like you will need to clean your carburetor.
Sometimes you can get by with priming it a few times, 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.
If the mower is over a couple years old, then I also 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.
When you clean your carburetor and remove the jet screws, count the
number of turns it takes to seat the jets from their original position.
That way when you go to put the jets back in, you know how many turns
they were in/out.
Please rate me, Thanks
Good Luck, I hope this helped

Look for air leaks in the gas line and around the carb , a bad gas cap will not let any pressure build up. It could be that too. Check also the fuel line and filter inside the tank. replace if needed.
www.ereplacementparts.com has parts for craftsman or the online Sears Stores.

Craftsman model 358.791042, gasoline weedwacker wont stay running

The high speed needle valve needs adjusting and it takes a special splined tool to adjust it. I currently am trying to find where I can purchase the tool to adjust the high and low carburator screws.

My craftsman weedwacker runs on propane. won't start

Can't solve your problem, but I just bought one, brand new from Sears, and it would not start. Took it back and exchanged it, and it wouldn't start either.
In playing with it, I found if I chocked the carb with my finger, it would start. In your case, you may be able to screw the idle/air screw in a little. It a little screw with a spring on it, on the side of the carb.
