secondaries wont open

Ok,
I know that the diaphram is good. Removing the check ball is sometimes recommended for use with small vehicles
I know that they are not opening as i fitted a cable wrap around the lever against the diaphram housing. The cable never shifted.
Never thought about the throttle blades hitting the inlet. Its a eddy Air gap. would have though that it would be fine for the Holley but i wil check.
