Ok, so here is the situation I have. I use the choke for cold starting, the bike gets warm, then didn't want to idle. I went to adjust the idle screw. However when I turn it, the hose connected to it turns as well, preventing the screw from actually turning. My thought is, there is something missing that should hold the screw or hose in place so it can be turned. Is there a spring sitting between the screw and the hose? I've been searching for a exploratory view of it. But have not found one. If anyone can help, I would greatly appreciate it.
