Rolls-Royce did produce a modification (Mrs. Cottle's Orifice I believe it was called) that went some way to helping the problem, however, they were never able to eliminate it as the Merlin didn't have fuel injection, as per the 109's Daimler Benz engine.

Her name is Tilley and Merlin it did get fuel injection. The injection was single point, not multi point as on the DBs.
