Dave here again (thread starter) about the SBC not firing on several cylinders... so as before I have 160+ per cylinder, new HEI, new carb, good wires and now new Autolite plugs. Same problem... not firing on at least one cylinder!! This is crazy. With my temp sensor #8 for example showing like 250 deg where most all others are around 450 pretty soon after startup. Also again, this is a totally rebuild engine with probably 2 hours or less of operation.
**My carb spacer does not line up the carb and intake manifold all that well. As I recall the vents are kinda offset. Could that effect fuel getting to different cylinders? Or any other ideas??

Thanks again, Dave
