My B20e is running rich, what to do? 140-160 1973

First easiest thing to do is remove the vacuum hose from the manifold pressure sensor. Suck on it, and if you can draw any amount of air through it, the copper bellows are torn, and it will have to be replaced. Next is to check the fuel pressure - 28-31 psi is about right. Also look for any air leaks downstream of the throttle plate, which will cause rich running. Check the manifold vacuum to be sure.
