DLE61 Carburetor heat block

Replacement carburetor heat block for the DLE 61 single 61cc engine.

Function: it is the heat block between the carburettor and the engine, which keeps the carburettor body warm and reduces the chance of carb icing.

The reason this ends up on an order: carburettor icing is a genuine hazard on a petrol aero engine, and the heat block is the part that mitigates it; it is replaced if it is cracked or its faces are worn.

Fitting note: Check both sealing faces and fit new gaskets — the block is only useful if it seals.
