my speedfight 2 starts up but cuts out strait away what needs to be done?

check there is petrol getin to the cylinder, clean your carb, pipes and filters. If there is still no joy it could be your cdi unit which I have just had to replace on my speedfight 2 because I had the same problem. The immobiliser kept coming on its self and cutting out the engine yours might be doing the same.

well it sounds like a fuel starvation problem you need to enhance the problems symtoms more for us to distinguish the real reason though.
