Well after six months of cleaning tank out, fitting new fuel line,pump filters fuel regulator and finding it still wouldn't run, so changing manifold gaskets, rebuilding carbs, still wouldn't run. new plugs, points cap, leads, rotor arm swapped coil got it to tick over. this week I have finally managed to get it to run -still a flat spot at 2-2500 revs but i am going to get it MOTed next week and get it on the road (its only done 200 miles in the last 5 years) a good run is bound to do it good.
