The combination of geometric frustration, extended hopping, spin-orbit coupling, and a disordered magnetic ground state make NaRuO$_{2}$ an attractive Heisenberg-Kitaev candidate material. Historically, NaRuO$_2$ has been challenging material to produce, even in polycrystalline form. Here we present synthetic efforts that identify propensity for Na$_\text{Ru}$ defects form NaRuO$_2$, revealing full solid-solution between Na$_2$RuO$_3$. We report the synthesis alloys along Na$_{3+x}$Ru$_{3-x}$O$_6$ solid solution characterize changes bulk magnetization electron transport as function Na-loading. Our results highlight importance stoichiometry control when investigating interpreting this material's physical properties.
