I think you answered your own question. If it was air tight, your engine would not run. No air, no combustion. You must have both air and gas to make a burnable mixture.

thanks for the reply. Thats what I thought It just seemed like there wasn't any air going through the TB, but there must be some air getting through.

Thanks again
