Ok. The sequence is the motor has a stepped pinion which engages with the idler wheels and the idler wheels then turn the flywheel which has the capstan on it. I've cleaned everything as best I can but at 7.5ips it runs slow and sometimes the whole system slows down including motor and will pick up after a bit or sometimes with a bit of help by rotating the reels by hand. Because it's intermeittent it's difficult to pin point the cause.
