I would appreciate your thoughts and help. I took apart and cleaned all of the parts on the carb of my express and then put everything back together, it starts great. However when I reconnected the throttle cable I do not have any tension and it seems like the engine is on full throttle. When I remove the throttle cable and hold it in my hand I am able to move the throttle pin in and out with the throttle handle as it should however once I screw it back into the carb the throttle no longer contracts and expands and there is no throttle pressure on the handle.
I would really appreciate your help.
