If raw fuel is coming out the exhaust when you spin it over, it might be flooded.
Remove the glow plug....open the trhottle all the way, and spin the engine over
for about 10 seconds. All the excess fuel should blow out of the engine. Let it set
for about 20 minutes to air dry out.

Now put in a good plug. The main needle should be about 2 turns out. It should run
if the fuel system is proper. Close the throttle and open the carb back up to just about
1/4 throttle and give it another try.
