The bernette 82 e moves very slowly, what is the problem? How can I fix it?

Check the pedal if it is still ok. Get someone to measure the resistance as you push the pedal. Otherwise, the belt on your machine must be worn out and needs to be replaced. Likewise, check on your bobbin rewinding clutch if it is fully home to the normal position.

I recently got an older bernette 334 ds serger and it doesnt look like it hss ever been used. i went to plug it in and run it and nothing happened only light came on

If it's old and has never been run, it will need a proper service fro the parts that have become immobile due to the lubricant "gumming up".

Off to the sewing machine shop for you!

Plastic spool holder for 334 bernette holds telescope thread guide screws in to attach to back of machine - this has snapped due to something falling on it have been told no longer availabe - machine is...

You could buy a generic thread stand aerial to overcome this problem.

These items are targetted at machine embroidery enthusiasts using multiple thread colours but could be easily modified to hold your 4 cones.

Or try and see if they carry this part.

I love my 334D and have paid for major repairs to it rather than replace with the lighter weight new models I found available.
