Fill the tank with fresh fuel

Leave off the glow ignitor/driver and open the throttle all the way
Place a finger over the carb and using you hand rotate the prop and while you are doing that you should start to see fuel moving through the line. Do this until you see it get into the carb.

Now close the throttle, attach the ignitor/driver and try to start it

Another way it to open the throttle, put a few drops of fuel right into the carb, cloe the throttle, attach the driver and try it

Also, with the throttle trim in the middle and the stick all the way down, you should see a very small opening when you look into the carb. This opening should be roughly 1/32 to 1/16th of an inch. If you do not see it the carb is all the way closed and will not allow any air into the engine which will not allow it to start
