Hello there, my suggestions are, use some choke or, there is a screw on the left-hand side of the carb with a flat-head on it. If you loosen that screw it allows more fuel through the carb. bare-in-mind you want the bike to sit (tickover) on as low revvs as possible (around 1500-2000rpm), but not too low that you stare the bike of fuel. a good way to test that your carb is set corectly is to sit on your bike at tickover, then pop it into first gear stationary, if the bike cuts out, adjust the screw so that the bike sits at higher revs, remembering you want the bike to sit as low as possible. sorry if this doesnt help.
