I really hate pumping my throttle to see the motion with the bowls full of fuel and I'm not going to start it. Just dumping fuel in there and letting it set.. from the little action that I did put on it it did look like those rods just force against the spring loaded doors to open it not to close it.. you really got a thing Edelbrock and thermoquad not Holley when you're looking at this. The only Holley thing on this is the secondary Jets and that messed up 45 degree angle down on the fuel Boss...
