Thanks for the replies folks. Got up this morning, took out the plugs and checked for sparks, all good, Primed the fuel system and made sure the pump was working (diaphragm type), then popped it back together, Caught after 3 tries and it fired up on 1, 2, 3 etc. But it sounds a bit rough, similar to a v-twin. Wondering if its maybe not running on all cylinders yet. Idle is slightly eratic. Could prob do with a carb balance etc. and its got the clutch rattle so i'll get that sorted out too. Apart from that its just going to be wee odd jobs to get it back to strength
