empisal companion delux 400?

this machine very sensitive to correct threading and timing.if you sure its tension take a clean lint free cloth and pull it thru between tension discs.to check tension take a piece of cotton and pull between tension discs while adjusting tension,this way you can see of tension discs work.not a lot of info to work from but i cant see what machine is doing its difficult you give solution
