Carburetor Rebuild

The car would start easily, then falter as soon as the accelerator was depressed. It seemed like a carburetor problem. The GT has a 32/36 down draught Weber DGEV (electronic choke). Upon opening the bonnet the first question was: "WHY? Why did the previous owner paint the air filter with red primer???" Or is that just really bad red paint? I can understand wanting to pait the cover. Weber air filters are poorly chromed and tend to rust,...but why not some rattle-can silver or a gloss black?
There was also a small leak from where the carburetor mates to the manifold. Dripping fuel so close to the hot exhaust manifold is a GT-inferno waiting to happen. That gasket needed replacement before attempting to restart the car. With two good reasons to remove the unit it was time to get going. The bay looks ratty but we're not going for "pretty" at this stage of the game.
Sure enough! Lots of rust had made it past the fuel filter and into the float bowls. It was likely clogging the jets and who knows what else. That's not just "varnish" from stale fuel, but actual rust grit from the old tank.
It was time for a complete rebuild so I purchased a kit from Weber Carbs Direct . The full rebuild kit was just under $25 plus shipping. I also purchased the top filter housing, air filter, and cover for an additional $20.00. Painted cover be gone!!

With the help of the Haynes Weber carburetor manual the tear down and rebuild was straight forward. I took lots of pictures and placed all the pieces in labeled sandwich bags to keep everything separate.

Here is it after cleanup that included a soak in carb cleaner and polishing of the air intakes and float bowl. Reassembly is well underway in this picture.
Now the prettiest thing in the bay, the carburetor is installed back on the intake manifold. No connections yet - I still have some other fuel-related work to finish after reading an article in the latest issue of MGB Driver magazine where Dave Dubois has an excellent article on fuel system improvements.
Next up: Reconnecting the fuel, air, and electronics for the carburetor, plus my final improvements to the fuel line. More on that in a week or two!
