The increasing levels of ethanol in fuel have led to a rise in the number of heat soak problems.

This occurs when the heat rises up through the intake manifold thereby warming a downdraft carburettor body to the extent that fuel in the float chamber expands, or in some cases, actually boils; the result is neat fuel in the manifold but an empty float chamber.

Downdraft carburettors, such as the Weber 32/36 DGV and DGAV, have always been supplied with a 6mm insulator block in an attempt to prevent this from happening. However, in some cases, that is no longer sufficient and greater insulation is required.

Webcon has announced the introduction of its all-new, UK-made 17mm heat insulator block, which comes with gaskets bonded to both sides. The blocks will suit the Weber 32/36 DGV and DGAV series of carburettors.
