Ok, so its not a Mustang, its a pre Mustang, 66 Falcon, but everything about it is the same as a 66 mustang.
I am pulling my hair out, rebuilt the carb, checked everything, and now no matter how I adjust the float, or the idle jets, it burns rich, black smoke bellowing out the exhaust, and runs like crap. I had another carb on it but found it didn't match the manifold, and there was an air leak. Funny enough i drove it that way for 4 months... (ya it sounded like it was sucking air, but i needed to get to work)
Any suggestions on what I might have screwed up? It was running fine before the rebuild, my points had closed, but I thought it was a gumbed up carb, and thought well its always good to rebuild the carb just as a preventative measure... Any Ideas would be apprecitated.
