Car started hesitating in the corners (fluttering).
it's a Methanol 4150 Carb. I replaced the Floats, needles and seats, Power Valves, and fuel pump (since I knew the spring was broken in it).It also has 97 Jets in it.
Now when we start the motor up, Methanol POURS out of the exhaust unless we move the front float as low as it will go. Borrowed another Carb, and it quit doing it. First we thought maybe I got the wrong fuel pump( to high PSI),we don't have a pressure gauge, but as I said it's fine with a borrowed Carb.

Any opinions on what I changed that may have caused this?

When you changed the needles and seats, did you put the steel ones back in? If you didnt the other ones are almost like a rubber tip, and the fuel will eat the rubber tip on the other seats. you may look at that area.

Would it do it that quick? We changed them last night and it started doing that.
