Flying along merrily this morning, perfect stitching as always from my Elna 664 ( and I was sewing mosquito net), started a new seam and after 4 stitches I just got a whizzy noise and the needles stopped moving.
I've rung the old boy I bought it from about 8 years ago and let him hear the whizzy noise over the phone and he said it could be the motor or the clutch. I happen to be in the Metrolops on Tuesday so I'm taking it for him to have a look - it may not be terminal.
