The black smoke usually means that the engine is way over rich. Clean the
plugs and try it with no fuel pressure. New engines tend not to seal until
they have run for a few minutes. I avoid this by starting the side seals at
zero clearance. As long as the corner seal and the side seal return when
compressed, that's enough clearance. The corner seal pushes the side seal
along as the engine runs, and in a short time the side seal will wear a
depression into the corner seal and pick up more than enough clearance. A
squirt of motor oil down the carb before you start will help seal things up
for the start, and won't hurt anything.
