Yeah this generator is great, even mine used to start on half rope but now after this resistance, i have to pull the rope then pressure buildup, then i pull it a bit more further and pressure is released then i leave the rope so that it gets back till end then pull it then it starts, still on one pull though...
Are you sure regarding the clearance? I think they are too much... I have currently set it at .15mm and .20mm, it might be only clearance issue...
