Ejection Handle Pulled
.. worked better once I removed the air-injector smog controls out of the exhaust manifold. !!
Boy, that was some primitive stuff, wasn't it? I had a '71 Chevy that had a TCS valve (Transmission Controlled Spark) that prevented the vacuum advance on the distributor from working unless the transmission was in top (3rd) gear. What a way to kill performance for the sake of emissions! Really woke up that old bucket when I ran a direct hose from the intake manifold to the distributor...
