The VMI 200 is designed to directly replace the spring mass, diaphragm actuator and mixing bowl in existing Impco 200/225 style Gas Engine Carburetors.

By providing a multitude of fuel inlet vanes and passages evenly dispersed throughout the low-pressure region of the venturi, the fuel is more evenly distributed and providing a more homogenous mixture to the engine.

This upgrade to an older gas engine carburetor can improve mixing and assist with the air/fuel ratio by keeping the mix approximately at a desired rate. It will still be necessary to control and modify the ratio with a AFR controller.

The VMI 200 includes a carefully designed venturi designed specifically to maintain a constant fuel mixture and any load by drawing just the proper amount of fuel for the specific amount of air that is being drawn into the engine. This will ensure that the ratio of fuel to air is constant and it will make the work of the air fuel controller much easier. If the engine is to be run in a lean burn mode, the improved mixing will extend the lean limit allowing the engine to be run leaner than it normally can with a traditional carburetor.

We recommend using the Continental Controls GV1 in conjunction with the VMI 200. This valve can precisely control fuel pressure which is ideal for fuel control along with a venturi.
