Is it sitting on the bed properly? I've had a few panics re possible damage to GC when not moved, + problem was simply being placed incorrectly on bed,
I remember reading something about your GC model + needing magnets for later machines/electronics. Did the previous owner have a punchcard or electronic? If the former might be You need to get magnets-am sure seen sites with fitting instructions.
However rather than me rattling on see address listed for professional information regarding magnets + GC, plus more:

Also www.daisyknits.com mentions kg88 + electronics KH900-970 needing- 'add sensors and book,' plus '
'additional rail over the top of the louvred rail and cut off the stoppers at the ends of the added rail.'
If you've got this sorted try asking on a yahoo MK forum, or put 'garter carriage' plus model no. into Google.
Hope you get it sorted soon without additional expense, they're brilliant machines-I live in fear of anything happening to mine!
