Thanks for the reply, I got it apart and found a new spring and pulley. I ordered it for $7.46 . I have several years in maintenance on locomotives and heavy equipment. I figured it was not worth buying the complete rewind and housing because of the age of the weed wacker. If it don't work when I get done I will put it in file 13 and will be out a few bucka

I see you've already taken care of the problem with your trimmer. These little engines can be a little bit different to work on compared to some of the more common models.

I got the engine back together. Starts and runs fine for awhile. After it runs I have a problem with pressure in the gas tank. I have changed the gas tank and cap, primer bulb, rewind spring and pulley before this problem started. I removed the filter cover and noticed smoke coming out of the carburetor when I give it a few pulls. If I use the new cap the engine floods and stops. If I use the old cap gas leaks from the vent in the cap while it is running but does not stop. There is a pressure build up in the tank. Could it be that the intake valve is not seating properly? I am out of ideas. It looks like the new cap has a check valve where the old one does not. I tried reversing the fuel lines but the engine would not start or prime so I know they were installed correct. Help!

I am sorry you continue to have problems with the trimmer. The cap does have check valve that will allow air into the tank but will not let air out. It is normal for the tank to build some pressure. If the engine is flooding after the tank builds a little pressure, I suspect the needle in the carburetor is not sealing. This could be cause by something stuck in the seat or the diaphragm is stiff and holding the needle open. I recommend cleaning the carburetor and replace the gaskets and diaphragm if needed. The link below will aid in this repair. I hope this is helpful. Please let me know if you need further assistance.
