I question the accuracy of what I've done, but here's where we're at. I ran to Pep Boys, because they had it, and bought a Mr Gasket tee and pressure gauge. I ran fuel line from the tee to the windshield and installed the gauge. I don't know if those 4' of rubber fuel line tee'd off of the actual fuel gives an accurate reading or not. But, at idle, it's showing about 8 psi (way too high). When rev'd, it'll drop to about 7 (still way too high). Before I install a pressure regulator, do we think this reading is reasonably accurate based on the tool and the way it's run? Also, would having too much pressure cause these issues? (I suppose it would be like having to little air, so I can rationalize how it would cause the engine to stumble.) Polara, I'm almost at the point where I'm going to swap the carb. I spend about $150, or so, I don't remember exactly, having this carb professionally rebuilt. I hate to just junk it. But, if it'll make it go, I'm open to the idea. I'm just not there yet. I'm trying the cheaper stuff first (which is, cumulatively, costing far more than a carb).
