    the rear large barrels are opened by engine vacuum, check to see if the large butterfly valaes are free moving, the top of the carb gets distorted and provents these valves from moving, let me know.

Are you saying vehicle is running on 2 barrels?
Time for a rebuild if thats the case. Kinda strange that secondaries are not opening. Make sure likages are not binding. Thats the only time I've ever seen that linkages binded.

Carburetor on my 85 Deville only one injector works what could be the problem


There may not be anything wrong. On a two-injector throttle body, the second injector acts similarly to a four barrel carburetor. On a four barrel, only two barrels supply fuel until you kick the accelerator pedal down hard for quick power for passing as such. At idle or normal cruise the second injector in non-operable. Only when you kick the pedal down (passing gear in old school terms), does the second injector activate.

DOES A 1987 305 CHEVY ENG HAS A COMPUTOR.


As long as it is a carbureted engine , simply change intakes and install your four barrel . Yes it is computerized , but will not interfere with carb swap .

86 ford 460 cu. in. Ford w/ Holly four barrle carborator secondary


On most models, the secondary barrels would only work if the primary are in wide open position, and even then the range of opening is small.
The engine should run past 3000 RPM on just the front barrels, so you may have something else going on.

Sounds like you have a vacuum leak,around your
new manifold or carburetor. No the timing will not be different between a two barrel or a four barrel carburetor.
