My Craftsman Weedwacker, Model # 358.791042 will not stay running.

I have replaced the spark plug, completely cleaned the carburator, drained and reserviced with new gas and it wont stay running. After initially replaceing the plug and gas, it would start up and only stay running if I feathered the the throttle but as soon as I would go full open it would die. I feather the throttle log enough to completely run through 1 full tank of fuel. So I removed and broke down the carburator and cleaned it throughly and reassembled and installed. Now it will start and not stay running even if I feather the throttle.. If I leave the choke on after starting it will stay running for about 15 secs than die.. Anyone have any other thoughts as to what the problem is? Would it be worth it to purchase a new carburator for $30 and hope it will work properly or is it time to get another weedwacker?

thank you for your question.

i am sorry you are having a problem with the trimmer. it sounds like you have a problem in the carburetor. to be sure the problem is fuel related, i recommend removing the muffler and checking the operation. if the engine runs normally, i recommend cleaning the screen in the muffler with carburetor cleaner and a wire brush. if the engine still will not run i recommend checking the condition of the fuel lines. if they are hard and brittle, i recommend replacing them. if the lines are fine, i recommend trying to clean the carburetor again. i found a video that shows how to clean the carburetor. click here to watch the video. if it does not fix the problem i recommend replacing the carburetor. the parts can be ordered from the following link. craftsman trimmer parts

i hope this is helpful. please feel free to reply below with more details if you need further assistance.

thank you for using manage my life.
