Could not find the exact model in the list--I am repairing a GS Moon 33cc scooter for my grandson. The unit is back together, I have a good spark, 80 lbs of compression, fresh 25-1 mix fuel, the spark plug sparks properly and shows wet with fuel after an extended crank with an electric drill. The carb needle valve has been adjusted from 1/2 turn out to about 2 turns in various stages. I'm stumped- it still won't start. Any ideas?
