Hi,

I also have a Thunder Tiger .46 Engine. For my case, my problem is a bit more simple than his. Why can't i choke or prime the engine? I set the throttle to idle, and covered up the carburetor with my thumb. After that, I turned the prop a 5~6 times but there is no fuel flowing into the engine? The line fuel line connected to the engine does not indicate any flow of fuel coming into the engine.

Can someone help me out. Thanks a lot!
