Thanks Guys. A warm welcome. Have removed the speedo gear from the transmission. It looks in perfect condition with the cable seating into the gear and no evidence of wear. So connected the cable to the speedo dial and turned it with my electric drill, the dial and cable seem to work fine.
All in all no solution, any ideas?
I've read that the precise assembly of gear to cable and cable route can cause problems could this just be the problem.
