Surging idle

[BRIELLY]

This afternoon I ran it off a seperate tank of gas and its still surging. I also tried unplugging the idle stabilizer and checked the fuel pump. Still no good. There seems to be a very large amount of oily gas leaking from the carbs when I tilt it up. I realize there should be some leaking from the carbs but when it forms a puddle in the splashwell it seems too much. This was happening before the idle problem appeared but could it be related and what would cause this to happen?
