When first started all switch positions work fine after switching to off all switch positions run full throttle

I found a paritally blown fuse. When the fuse blew metal pieces ended up partially making contact. After replacing the fuse everything worked great.
You need to rebuild the carburetor. You will need to go to an outdoor power & equipment store of some kind to get a carburetor kit for your specific trimmer. It will come with various gaskets, (some of which you won't use), a needle valve, and a small screen that goes in the carb. Replace all old parts with new. New primer bulb is sold seperately. When you have the carb. apart, you will also need to clean the small ports with a Den Tek Brush (used for cleaning teeth). Use carb. cleaner when cleaning.

About the only thing you didn't mention was the starter itself. You could have it tested. But before that, try to see if you have power on the small wire to starter solenoid on the starter, when key is held in cranking position. Pull the small wire off and check for power with a multimeter or a testlight while someone holds the key in crank. This is the signal wire from ignition switch that closes the elec. contacts inside solenoid so the starter gets full power from the battery to spin. (This wire also is in the circuit with the clutch switch and the starter relay.) If you have power on this wire in crank, it is very likely the starter is bad. If there is no power, check that circuit out. It is losing power somewhere from switch to starter solenoid. Good luck.
