Holley/Demon Carb stumble

mab work in conjunction with the emulsion bleeds. A smaller mab starts later and gets richer. All the old holleys had two emulsion holes .026-.028 and worked great. Use the mab and emulsion size to get a flat fuel curve and jet it to maintain what you want to run at WOT. I run a Mighty Demon and it works great.
Trashing a carb brand is easy. Reading a plug after 1 year and basing performance of a car with a 2000 foot DA change is ridiculous.
