Holley/Demon Carb stumble

Honestly, at this point I’d just put the Demon back together like it was when it worked as good as it ever did, and reuse that as the baseline.
It has crossed my mind but it did the same thing that is happening now. (haven't found the problem) Before it all said and done it will be back together and a proven carb......the proven part is what i haven't found on either carb.:BangHead::D

I sent a email out to proform on there metering block. waiting on a replay.

Time to wrap up my stitches on my thumb and see what i can figure out on the current combo.
