Runs great, blower and trimmer heads will not turn/work. Tried using the blower attachment and the fan turned very slow

Probably something wrong with the mount. You have a photo?

Check out the drive unit from the head of the motor down to the trimmer head it may have a problem.

Hi Jim Kamph...
You have a broken drive cable inside of the trimmer.You will need to replace the drive cable

It may be that the drive shaft is broken, or not engaged to the engine. Make sure the trimmer attachment is locked all the way onto the shaft coming from the engine. If it still doesn't work, check by seeing if any of the other attachments work when you put them on. If they do, you know the drive shaft in the trimmer attachment is probably broken.

There isnt anyway to turn the head the other way round as its ment to run that way just go round the edges the other way

When the engine was running there was no drive to the cutter head. It appeared that the bearing at the bottom of the flexible drive shaft had worn away from the three crimped marks in the exterior drive tube and slipped down, thus the flexible drive shaft inside the main tube was not reaching the cutter head. I made up an exterior tube that just fitted over the main drive tube. I Drilled a 6mm hole through the exterior tube and the main drive tube into the worn bronze bearing. I then brazed a 6 mm nut onto the exterior tube and screwed a 6 mm bolt and lock nut right into the bearing inside the main drive tube. This stopped the bearing moving down and away from the interior flexible drive. The trimmer then worked as it should do. Good Luck, Tony Hillyard, Pleinesa Oeuvres, France

cable in the shaft is broken

the blower only running on 4 is usually the blower resistor
