Got my Knuckle engine back from the builder. Installed carb (M74B with Cotten's float and peek rings), manifold pressure tested. Bike starts but i need to bring the idle needle down to 1-1,5 turns only, to idle smoothly and take gas nicely when turning the throttle. Bike takes off in first gear but cannot shift to second gear since bike doesnt take gas anymore ... Hardly brought the bike back home (anyway, was only a couple of meters). Bike starts afterwards but doesnt idle anymore properly, shoots quite nicely through the exhaust ...
Any help is appreciated.
