3F ENGINE STALLING

1992 Toyota Landcruiser • 38,000 miles

Hello, I have a problem with my 80 series cruiser. Its a 1992 model with a carburetted 3F. I noticed it stalling when driving, and have been able to consistently re-create the problem when stationary. When I hold the motor at ABOUT 1200 rpm (sorry no tacho) the engine stalls for a second before recovering back to 1200rpm. It holds this rpm for another 5 seconds before stalling again. This will keep happening as long as the engine is held at the same rpm. It happens stationary, and when the engine is loaded (at about 80kph in 4th and 100kph in 5th). The engine accelerates past this dead spot with no obvious problems, and does not seem to be lacking power. I have replaced the fuel filter, and inspected the plugs, points, dizy. I have also noticed a large amount of vaccum in the tank after running, and have not discounted a vapour lock. The engine and t-case were re-built at 302 000km. Any help will be greatly appreciated.
