Query: Solved my vapor lock issues and then some!

I got this because my carb was heating up and boiling the fuel, causing vapor lock! Not only did this spacer solve that, but now the engine starts up much easier and is noticeably more responsive even when cold. I bought this after returning a piece of junk spacer, and the difference is night and day. This one comes with top notch gaskets and studs that are the right length.
