All of that is pretty much expected....HOWEVER.....what you probably have now is: Too rich at idle and WAY lean at higher speeds. Just simply plugging that hole in your air box will put things back pretty close to normal......so you can drop the idle back down and stop using the choke after it warms up good.

One should ***NOT*** monkey with the air filter or housing unless you are also going to re-jet the carb. What you are doing gains you nothing. It comes lean from the factory and that hole in the aribox makes it even LEANER. Not good. Moreover, it lets unfiltered air into the engine. :skull:
