Read the beginning of the second paragraph and their parts and see if it makes sense: '...which delays..' '... just about ready to stop delivering fuel...' is a fallacy fumble after fumbling the basic theory. Take the whole book as a grain of salt peter, because this is way too simple, even a dumb dick like me can grasp the 1-ATMO. Here is how you breakdown an Open Hole vs. Vacuum:
1. Nature will fill a void faster than the speed of sound [at least] if not at supersonic speeds to wipe out a vacuum pull back to 0, or zero, or 14.7psi, or 101.3pa, or other nomenclature explaining the 1-Atmosphere.
2. There is no door, gate, guillotine, or other mechanical devices about to close the hole and 'stop delivering fuel.' (begin laughing) under vacuum... Get it so far?
3. The fuc is dis delay bullshit? All circuits pull fuel/air out of each hole at the first suck of the piston going down, and every last rpm no matter the engine speed. Theory says, you throw you dick past that carb intake and if it's in the way at 5,000 rpm, it will tear your foreskin off kind of vacuum pulling back to 1-ATMO.
Conclusion: Someone needs to dis prove my foreskin of the piston pullers. That book is as lame as reading this post.
