Glad you asked about this kikkegek. I've wondering about how to set this up myself.

Always use a dual return spring- a "spring inside a spring" as used by many OEM's is an excellent type of return spring to use.

Below is a simple $9.00 spring and bracket sold by Mr. Gasket (P/N 720-19) that might work in your situation, and shows the type of spring to use:

Hey cobalt327,

Does the bracket mount in a specific place or does a hole have to be drilled in a specific place to install it? Or if that's too much work, would the setup pictured below be a better choice? It is a manifold-mount universal set up (attached are the installation instructions in pdf). I couldn't find one that was Q-Jet specific on Summit.
