Does the choke normally spring back to off? Because I have to hold the choke on with tumb as soon as I release it springs back to off. Is this normal or do I have a problem?  On a 2005 1100 v star 

My 2005 VStar 1100 Silverado will stay where ever I set it. 

That what I thought but mine spring back I have tried to fix it. but don't seem to know what the cause is.

When I had a choke it stayed put. Cable may be binding up.

After it springs back is there any free play in the cable? Might just maybe be part of your problem.

No free play at all and don't feel any kinking in the cable when pulled on. Is there a spring on the carb that bring it back? I am thinking that the cable May not be tight enough to hold it?

There should be a little free play/slack in the cable when not engaged. Something ain't right.

Check the book.

No spring on the enrichener ... there is no butterfly like on the standard carb.. it's just an extra circuit for more fuel

Hey Ron!
