Being a well organized workshop I had no trouble finding the ancient GKN box of the appropriate screws....but found 6 Amal carb jets in there as well.
These jets were for a Bonneville I sold in about 1982. Since then I have moved house twice & business premises 4 times, and it's been over 10 years since my furniture / joinery business and motorcycles last co-existed at the same address.
I might now be tempting terrible fairy revenge but can report the Shed Fairies had failed miserably.................
I didn't ever know the jets were missing and had never had to look for them.
