Holley/Demon Carb stumble

I bought a Proform base plate
Proform Billet Throttle Base Plates 67156

hope that is the right one

Might not be. This is to go with a 750 proform body?

When i took the carb off this time i noticed that the butterfly/transfer slot was less than a square on the primary side and the secondary side had one blade that just showed the beginning of the transfer slot, and the other had it completely covered up.

Not that unusual.
Can extend the short slot with a razor saw or thin file, or chamfer the bottom of the throttle blade. Third option is a bit more work, but clever. Run a set screw in to shorten the slot. That was posted by someone RFS forum.

Another reason i want to replace it is that this was a used carb and had holes drilled in the butteries, that are to large. I would soldier them up and re drill, but either the throttle shaft is bent or the the butterflies.

Holes to no holes will change the whole transfer slot relationship. Not saying good or bad in this case. Just that it will be like starting over as far as setup goes.
