In the diagram are the parts behind the Driver shaft "Shim" washers of varying size? As well as the 3 choices behind the race starting with 266? Without a Part# list and description, hard to know.
Thank you and I kinda heard that around town as well. Wanted confirmation. That will get the hook in place, but, in addition, the hook driver is need of adjustment as well. There is no needle support/guard and the needle is just floating out there.
The clearance from hook tip to Needle scarf for the hook to to catch the loop. Most clearances should be about 0.1mm and this machine is way greater than that.
Hook to needle clearance is too great, little less than 1/16". Experiencing skipping, of course. Can not find anything from Adler books or videos on how to adjust clearance. Much different set-up than a Class7 Hook adjustment.
