Hello, I'm running a sbc, with a 471 blower. I just purchased a demon blower carb and set everything up. The car seems to run fine, but when I turn the car off I notice a small amount of gas leaks out of the bottom of the blower. It appears to be coming out of the base gasket on the blower. It doesn't appear to leak a drop when the car is running. Just when you shut it off it seams to spit out, what I would consider unburned fuel. I'm not sure if this is a gasket issue with the blower, or some sort of carb setting. Having little to no experience with this I haven't really fooled around with the carb. I was just looking for any suggestions of what could cause this problem. I am trying to avoid taking the blower off to put in a thicker gasket, but If need be I guess I will have to. The gasket that is in there is brand new. thanks
