<VV> Choke Pull Off

[Rudy Korb]

Hi all, need some help.  I have a 67 Monza 110/pg and the right (as your facing the engine) choke pull off has a rattle sound when in gear and idleing.  I thought the old one was bad so I replaced it and the new one does the same thing.  The left one is just fine. The rattle stops when you give it some throttle, but returns when you get back to idle.  At idle without being in gear and higher rpms, it works great.  Just seem that this occurs at low rpm.  What do I need to do???  
   
  Thanks for your help,
