Engine flooding was a common problem with carbureted cars, but newer fuel-injected ones are immune to the problem when operating within normal tolerances. Flooding usually occurs during starting, especially under cold conditions or because the accelerator has been pumped. It can also occur during hot starting; high temperatures may cause fuel ...
[citation needed] The electronic versions have a throttle position sensor that is mounted inside the carburetor body, actuated by the accelerator pump lever. Quadrajet carburetors have mechanical secondary throttle plates operated by a progressive linkage; the primaries open before the secondaries, and use on-demand air valve plates above the ...
K - single jet type carburetor (such as the Solex-Cisac carbs), typically with automatic choke; G - LH2.4 Jetronic but without catalytic converter, CO adjustment on the AMM (similar to LH2.2 Jetronic). Some models without O 2 sensor, others with O 2 sensor which requires regular replacement at intervals due to lead fouling. For markets in which ...
Carburetors are provided with a float chamber to provide a constant hydrostatic head of fuel above the carburettor's metering jets, thus a constant pressure. The float chamber itself does not vary the pressure according to demand, but it does vary the supply flowrate with demand, to keep this pressure constant.
A carburetor (also spelled carburettor or carburetter) [1] [2] [3] is a device used by a gasoline internal combustion engine to control and mix air and fuel entering the engine. [4]

Vapor lock is a problem caused by liquid fuel changing state to vapor while still in the fuel delivery system of gasoline-fueled internal combustion engines.This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling.
The hot film MAF sensor works somewhat similar to the hot wire MAF sensor, but instead it usually outputs a frequency signal. This sensor uses a hot film-grid instead of a hot wire. [3] It is commonly found in late 1980s and early 1990s fuel-injected vehicles. The output frequency is directly proportional to the air mass entering the engine.
