Review on 🔥 Demon Street Demon Carburetor 1901 with 625 CFM by Joseph Morris

I bought this carburettor to replace the original AFB on my 1966 Pontiac 2+2. It works well right out of the box. On this particular engine I had to reroute the PCV lines and use a carburetor base fitting instead of the factory intake manifold fittings. This was a relatively minor change that actually makes for a cleaner look as the PCV duct is now hidden behind the air cleaner. The e-choke works very well. The electric choke further reduced underhood clutter by removing the heater tubes that ran from the manifold to the carburetor. The only issue I had with the choke was having to make my own wire. The cable in the carburetor was so short it didn't even reach the firewall of my car. I know copper is getting more expensive, but I'd happily pay a few bucks more to have a useful wire in the kit. I haven't made any adjustments other than adjusting the idle mixture and limiting the idle. On this particular engine (+0.040 421) the secondary seems to be lean so it may need to be flushed again. The main side of the carburetor appears to be properly adjusted. Response around town was excellent and the car starts immediately, both hot and cold, even after a few days of inactivity. The old AFB is completely dry in 3 days and requires an extra twist to refill the carburetor. Overall, I'm very happy with this carb and would recommend it. Incidentally, with this type of carburetor there can be problems installing the air filter, but my 14 inch drop-base air filter from GM Performance Parts fits without any problems.
