WTF? You've just DUMPED a large quantity of air. The 7M doesn't use any sort of meter which can see this loss... thus many people experience problems. And vacuum has nothing to do with it at all... Interestingly some people just see heavy richness and some occasional backfiring (postignition). If you have a fuel controller this can usually be compensated for.
