I have issued this question already in a wiper motor issue post. Where it actually didn't make a lot of sense.
There is obviously a linkage from the vacuum advance to the vacuum line coming out from the carb. The connection was disconnected. As a matter of fact, the vacuum line from the carb was sealed. The car was running beautifully without any issues.
I stupidly connected that line, took away the seal and connected the metal line from the vacuum booster wit the tube going into the carb. The result, the car is now running really bad, acceleration was an issue. It felt like he wasn't getting any fuel or not enough fuel at some stages, there was total stuttering taking place etc.
Questions:
What is the vacuum booster actually doing? In theory of course I know that. But how can it be that a disconnected link worked out better than when the vacuum booster was actually linked to the vacuum line?
So, could you just drive always without the vacuum booster being connected?
Is the issue that I experienced - so vacuum booster connected, acceleration a real problem - maybe an indication that I have a problem with my cars vacuum performance?
thanks
