Choke

So far, the posts I've made showing the bike running have been only with the choke on. The choke is simply a mechanical door that restricts airflow through the carburetor. I've had a running theory that the problem might be partially related to the fact that I have had the air cleaners off of the bike. The air cleaners on this bike are fairly restrictive, they are oil soaked foam elements. Today I reinstalled them and tested. It now idles fine with the choke off. So I guess there isn't a problem. Nice!
