Hi, i found the oring on the shaft, the spacer just slides on with no resistance from the oring, i removed it and it is cracking, perished, replaced this with a new 1 and the spacer now has a posative grip from the o ring, so fingers crossed all should be good, will be rebuilt by w/end for testing

Got it all back together only to make a school boy mistake and put a longer bolt in the kick starter and holled the casing, not happy and now have to strip the whole lot down again and try and find a welder
