Need help with edelbrock 1406 carb

Very helpful this is. It looks like I have a lot of orifices to check. Different symptoms though. Starts right up, idles good although smells like it's on the fat side, in gear and part throttle not so good, give it a little pump on the pedal, smooths right out briefly. The hot rod does not have the stock fuel tank in it. It appears to be well constructed, but no idea if it's plated inside, a magnet won't make it down the fill spout to check for rust particles in the tank. Clear fuel filter is installed now, will see if any junk is visible in the fuel.
