Hello to all. I know someone has posted something about these in the past but here we go. I am in the process of cleaning up the engine bay area. Engine runs rough right now. I have been thinking or either rebuilding or replace with same q-jet on the 307. My thing is where do you recommend of either buying the rebuild kit or carb? I have the 17084254 q-jet on my 86 cutlass supreme. I appreciate the info and look forward to all the comments or concerns on this.
