MGB 1976 MGB Roadster for a patient.

A pal has brought his MGB here for me to get running, I've worked on it in the (distant) past. First issue was the half-and-half mixture in the fuel tank: half fuel, half WATER. Drained that all out, threw a bottle of HEAT in there followed by a half-dozen gallons of actual gasoline.

Thing has a Cannon intake with an IDF/DGV Weber mounted,that came off and got a total going-thru. Had to replace the float valve. YUK!!! green and gobber'd up mud. Manifold had a frog pond in the base under the carb, too. NO idea how they got it to run long enough to get it here!

Now looking at the dizzy, it has a coating of "frosting" of some fuzzy funky description. Looks to be corrosion.Don't let 'em sit for months outdoors!

It is amazing how much abuse they will take and still run at least a little.

Heck, I found out that an MGB will run (sorta) on only one cylinder -- when you forget to replace the 1-3 leads after doing an oil change for instance. Not that I'd ever do that.

I have the same manifold and DGV carb on my '69 MGB. I despise the way it looks, but it actually runs OK.

I bought a set of HS4s (+ MGB manifold) for cheap, but I think I'm going to fit them to the 1275 on the race car instead.

I know what you mean about pond scum in the carb. I bought that '73 Midget about a year back and the DGV in it was filled with greenish goobers. I pulled the 1275 out (also using for race car) and dropped in a 948.
Cleaned out the DGV plus swapped the gas tank (it was unbelievable) and runs fine (for a sub-liter car with a goofy carb).
