HELP PLEASE hood scoop and carberatour problems?????

[Ryan Dillman]

I put a new scoop on the roadster over the winter and went racing this weekend and had a lot of problems with the air pulling the fuel out of the vent tubes on the carberatour. The carberatour sits about 2 inches from the top of the new scoop and the front vent tube sits about 3/4 of an inch from the top and the rear vent tube sits about 1/4 of and inch from the top. the first run the car surged in and out from about half track on and only went 9.67 @ 157mph in super gas trim. Then i made some changes and no improvement. I run a under the carb dedenbear stop and took it off and that gave the carb about 1 inch to 1 1/2 inches of more clearance. the first pass ALL OUT it went 7.84 @ 167 then i used a piece of rubber hose and put it on the vent tubes with a small notch in the middle and the car went 7.77 @ 171.40. Im trying to figure a way to use my under the carb stop for super gas without having to cut the new scoop out and installing another one. Any ideas would be greatly appreciated.
