Whats the best carb?? I'm old school - mechanical fuel pump and carb. I have a Holly 850 double pumper and a holly 750 currently on the car that is leaking. Both seem to require a lot of maintenance and fine tuning. Any recommendations for a good "trouble free" carburator? At this point, I'm thinking of just getting a different brand. Hopefully something way simpler than the Hollys that I can install out of the box.
