Carb issues

No doubt some odd things seem to be going on with the fuel system/carbs, and I can't really add much to what's been said. But, if you run out of options to try, maybe? your starting issue could be voltage related at the coil/ignition system. The fact that the volatile carb spray gets you going makes me wonder. Just something else to look at if all else fails.
I'm running points gapped to spec,can't remember off hand what that is though.The fire is strong and I did put a supercoil (the big yellow one)on it to make sure I was getting plenty of fire but removed it because I don't have a mounting bracket for it.The plugs are autolites 64 I believe which I plan to replace shortly.
