This week end I started driving the B for the first time in about 4 years! We had a couple of false starts and we fixed the last major one this weekend by replacing the gas tank, the fuel lines and rebuilding the weber DGV carb. It was a great time finally being able to drive all around and enjoy the car. However there are a few issues. The main one being it's lack of performance. This is my first old car, before this I have owned a 1986 Buick Regal, a 1996 Oldsmobile Bravada, a 2000 Chevy S 10 and a 1995 Jeep Cherokee. All of them had 6 cylinders except the S 10. I didn't expect it to be fast but it's actually quit sluggish and it won't go over 40 with out a little bit of shuddering or maybe you'd call it pulsing? IDK. Any ideas how to fix this? I know MGB's have been known to do almost the ton, but mine won't really do much over 50.
When I rebuilt the carb I blew out all the passages with compressed air and replaced all of the gaskets and whatever else comes in the DGV rebuild kit that Moss sells. I set the float level to what it should be and adjusted the idle to about 900 RPM. I did notice that one of the Auxiliary venturis was a tiny bit loose. Would this cause the extreme lack of performance?
Also, before doing all of this I have done the following to the car mechanically: New Gas tank, and fuel lines, new cam, lifters, timing chain, timing sprockets, new distributor, new coil, new head gasket, new valves (which I lapped in) new valve springs, new water pump, and a 160 degree thermostat, new brakes all around, new wheel cylinders in the back, new brake disks in the front, new parking brake cable and I rebuilt the master cylinder. I will also note that the engine in out of a 1978. Any help would be greatly appreciated.

It took a very long time but the dash in my B is all done and working. My father and I started out with the metal backing from a '78 dash, welded up the top "pad" it's not very soft since it's made out of metal, and spent endless hours with the drill press making the engine turned aluminum cover. We also made a new glove box door and glove box. The little white knobs control the head lights, wipers, dimmer, choke, hazards and the vent. The small gauge between the tack and the speedo has indicator lights for the signals, alternator and the high beams. My father made the steering wheel by stripping an old B wheel and removing the spokes and replacing them as you see, he then cast the hub and rim out of plastic and made a horn button. The heater control is out of a '53 plymouth, I adapted all of the MG heater controls to fit in it. All and all it took about three years to make, that includes time spent on the rest of the car. This was probably the most time consuming single piece of the whole car.

The B is done. Just gotta get it registered.

Started putting the B back together after over three years of being in pieces

I started painting my B about a week ago, it's Old English White

Over April break I made some new parts for the interior of the B. The best part was laying out the engine turned aluminum dash insert.
