Hi so I just put my 400ex back together and it is not starting right. The carb leaks gas from the air filter connecting tube, and it only runs on choke. I cannot bend the stupid tube onto the carb and it just does not want to bend where it is supposed to. I dont know if that is the problem, if it is running to lean because of this, or something is broken in the carb. I took it off and sprayed the inside with carb clean, but did not take anyrhing apart. Any help would be appreciated.
