i have run into a bit of a problem. i was rejetting my carb on a cat 500, and when i re-installed it i noticed my air intake hose didnt fit tight. i bought a new hose, thinking maybe by some freak chance the old one was stretched, but.... it was loose also. i got a service manual to see if i was missing something, like a bushing or something, but nothing. HELP!!!!!!!!???????
