For my application, do I need to use a gasket between the throttle body and the insulator block when re-installing my carb? The gasket that came with my kit will be blocking a small hole in the bottom flange of the carb. There is a notch on my insulator block that would allow this hole to vent into the intake manifold.

this passage is shown at the bottom of the picture as "M":

I ask because, when I took the carb off, there was a gasket (same as the one that came with my rebuild kit) there that blocked this passage.

Also, my power valve check ball spring "L" looks squashed a little, but my rebuild kit didn't come with one....What to do ???
