I'm an old hot rod guy and have never messed with cars from the late 80s, early 90s with their bandaid approach to emissions control. My new to me 91 GW is a total learning experience. The flaps in the air cleaner raised a couple of questions.
As I understand it the outer "door" opens and closes to mix pre-heated air with the airstream. I'm assuming this improves the engines emissions to some degree, but I can't see how it would have much effect on the performance of the engine if it never opened.
The inner door should open when the ignition is on, if for whatever reason it does not open I'm guessing it would choke the engine to death. I can't really see what benefit this is to the engine other than MAYBE reducing evaporation from the carb when the engine isn't running. Am I even close to right in my thinking?
I'm planning on keeping this GW and I live in a state that has no emission regulations to deal with so my main interest is having a decent running, simplified engine.
On a different subject has anyone had any experience with the 2150 available from TGW or any other vendor that offer refurb or new units?
