DLE55 Carburetor

This is the carburetor for the DLE 55 single, a two-stroke petrol engine for larger sport and scale models.

The part itself is the carburettor, which meters fuel into the intake air.

Why it is replaced: carburettors are replaced when the needle and seat wear or the throttle shaft becomes sloppy, and on a petrol two-stroke a lean-running carb is a real risk to the engine.

Fitting note: Check the manifold joint and gasket, and reset the needles from a known baseline rather than where they happened to be.
