Morning everyone, has I had planned on Saturday the wife was out getting her feet nibbled by fish??????? but on the plus side I had a day to sort out this 'box. Armed with the info from Bill and Adrian I had the kickstarter of the mainshaft and loosened the inner case pulled it back until the selector dropped and then repositioned with the dot 1 out, tightened up used the screwdriver to check and low and beyond 4 cogs and neutral. Rechecked and still okay, I was like a dog with 2 whatnots, ie extremly happy!!!! the neighbours must have thought there was a banshee in the shed or worse with all the shouts . Anyway end cover on and the gears clicked absolutely cleanly I was made up. I had to make a gasket and that was the longest part to getting all together. After an hour I had it all together oil in and ready to try . She started 2 second kick ,would have been 1st time but for the cloth in the carb!! tried the gears and they moved beautifully very positive ,very light and quiet ,my god it had been knackered before I hadn't realised how bad but it was still working. So I'm very happy and would like to thank everyone for thee thoughts and advice,particularly Bill and Adrian now just MOT it and then it'll be business as usual, best wishes BobH.
