My 2150 seems to have had a choke tube at one time. I also noticed what looked like a plug in wire for the choke? Did these things have an electric and a choke tube? Its possible a previous owner put the wrong choke cap on it. I think I can rig up a choke tube for the headers but what do you do for the hot air box for the air cleaner intake? I'd really like to keep my stock air cleaner setup.

 

I have capped the tube connection & used electric choke with good results.
