I have a 74 1/2 MGB. I usually start it up a couple times during the winter here in NC, and come spring, it'll fire right up and run like a sewing machine. Not so this time. The battery went stone dead, as I did not start it over the past couple months. It turns over but will not idle. I placed some gas in the carb (Weber) and it'll crank but then die. I'm only 3 min. into the video, so hopefully will pick up something to help me. I really don't want to tow it to the mechanic!

I had a similar issue and ended up having to rebuild both the carbs as well as the fuel pump. It will start right up now but gas now pours from the charcoal canister so I am still trying to diagnose myself. I hope it goes smoothly for you! Best of luck
