Subject: [CR]Technical help needed for coaster hub

Dear All,

I have a problem with the Eadie coaster hub on my 1906 Royal Enfield path racer. I'd like to ask the list for some technical help on this one.

the problem: when the hub has been coasted/freewheeled/not pedalled the drive does not engage as soon as normal pedalling is resumed. What happens is that the drive freewheels *fowards* for maybe 1/3 of a revolution of the cranks. This is especially disconcerting when sprinting or honking uphill. Fortunately I already have all the kids I ever need, so maybe not the problem it would be for a younger man. The merest release of pressure on the pedals is enough to cause the slip which makes normal riding rather tedious. This plagued a veteran cycle race at Eastway circuit in London last year. There is a demonstration race at Herne Hill in London on Easter Friday, so I'm keen to get the thing fixed for then.

the hub: the design is the bog standard helical screw/tapered cone design. I've had the hub apart and all appears well. The hub was well lubricated and maybe that is part of the problem. Is there any part of the internals that should be kept grease free. Any help gratefully receieved.
