Hi, real noob question here. I have been given a 2nd hand trainer by my brother. Its a Thunder Tiger, with the pro .40 motor. The plane is in very good condition and only needed a radio and reciever to be complete. Now he told me he has not run it for over a year. while trying to start it (not going to fly it just yet, just want to run it) I noticed why it won't start, no fuel is getting into the carb. Its blocked somehow. I have been into RC nitro cars for many years but have zero idea on plane motors. Is there some type of fuel cutter or has something seized? (My brother is in the army and I can't get in contact with him at the moment).
Also is it the same story for turning them off as cars? Squeezing the fuel line or blocking the exhaust?

any help really welcome, thanks.
