With the aid of detailed stellar model computations, we analyse the consequences of applying a mild overshooting to 1.0 M to 1.2 M stars with solar metallicity. It is shown that solar models with a small convective core can be constructed, resulting in a decrease in the 8B neutrino flux that can amount to 30% relative to the value obtained in models without convective core.
