G'day Alan and Ian,The reason I asked about a kill switch is I thought it might be easier than fiddling trying to hook up the decomp lever which isn't there I can only see something into the crancase that obviously had a cable running through but then thats it I'm not that clever in working out how a decomp lever works or indeed how it hooks up.The books I have are very short on info so can anyone help,by the way Alan the bike you would not recognise it should have some photos soon and the clutch thrust bearing is something to be admired your brass ring with a centre spacer and ball bearings inserted on the face magnificent piece of machining by my buddy.another couple of weeks it should fire up hopefully can't wait Santa has come early I'm like a two year old with his first meccano set.
Regards Bazza
