Holley 20-92 Street Warrior Fast Idle Solenoid and Bracket

I liked that this kit has what you need to install it on to the carburetor, but...The screws that come with it are too big for the per existing holes in the throttle plate. (Mine were 8/32 thread) Holley supplies 1/4-20 screws. not a big deal. The problem is when using this kit for Holley model 4150 with a racing billet throttle bracket assy that bolts up to the drivers side of the carb. The return spring assy. interferes with the solenoid bracket assy. The throttle bracket either needs to be modified or a stock bracket needs to be used with a modified return spring.
