You've covered a lot! Sounds like the fuel pump and fuel filter may be the way to go. Speaking of fuel, one thing you might consider with a 1406 is a fuel pressure gauge. I installed one as I wasn't sure how my Mr Gasket fuel regulator was calibrated (or working), and the mechanical fuel pump was pushing gas past the needle & seat in my old 1405 - bad gas smell in the garage & carbon soot in the exhaust - but no more now. This is a VDO P/N 153002 - made in the USA! ($21.99 at Summit). You can see in the pic that the regulator is set to "4", but the gauge is reading slightly over 5 psi...probably still OK for the Edelbrock AVS2 I'm using. Awesome carb BTW. Best wishes on getting that surge figured out...I know how frustrating a nagging problem can be!
