Holley/Demon Carb stumble

Ok i was thinking that it was some screw you drilled in to the transfer slot in the bore. You know the the one you set square in the bore with the butterfly
also no drilled and tap for the PVCR
Pic on the way but one question
how does restricting the transfer slot help make the booster come on sooner or transfer hold on longer.

It doesn’t. I was saying opening the primaries and secondaries 1:1 will keep it on the transfer slots longer. I’ll see if I can find a picture of where the T slot restricters go. I use 10-32 brass set screws for those. You can get away with 8-32 but you may not be able to get the hole big enough.
