Well I got them all cleaned up, ordered new batteries and started looking them over. On one of the planes the throttle body is frozen. I diconnected the pushrod and gently tried to break it free. I didn't want to froce it so I really didn't put alot of pressure. I was going to take the engine off of the mount and soak it in something but I'm not sure what to soak it in. The engine is a Thunder Tiger 4 stroke.
Thanks for your help.
