That was me on the base gasket. There are so many variations of this carb and I've found the several of the kits out there don't have the correct base gasket for the early carbs. Once you get it back off and apart you can usually see what is wrong in the gasket match up or lack there of. You aren't expecting the gasket to be wrong so it doesn't get your attention the first time around. Seems like it's something to do with a tear drop shaped hole....
