right just been out to it again and sprayed the crank seal fly wheel side, base gasket intake manifolds with carb cleaner no change i have also swaped carbs but the problem is still on the left side so that rules out the jetting i suppose .
at idle it pops on the left side and not get hot but if i raise the idle useing the throttle or blip the throttle it seems to run but blows out a lot of white smoke
bloody confusing if you ask me.
