My friend has a '68 Runner that just plain will not work with that 750. It was a stock engine but since the installation of a Comp XE268 the problems with it have been exacerbated. He put it away for the winter with it actually running good and pulling pretty hard after he spent a ton of time cleaning and retuning that pos carb (but lacking the response it should have had still). Yesterday I went over to visit. He fired it up and we took it for a ride. It had no power and would not idle, just like right after the cam installation.

Luckily we tracked down a correct AVS for his car and are waiting for it to come in so he can finally ditch that POS.

Now I need to pin those needles, got to feel that heat
