MANIFOLD HEAT CONTROL VALVE

The Manifold Heat Control Valve Forces hot exhaust gases up around the base of the carburetor and intake manifold to warm the fuel-air mixture. If additional heat is not supplied, the gasoline can easily condense back into a liquid as the fuel-air mixture comes in contact with the inner surfaces of the intake manifold. This improper fuel mixture typically causes rough idle, reduced power on acceleration, and engine stall.
