  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 a
challenging material to produce, even in polycrystalline form. Here we present
synthetic efforts that identify a propensity for Na$_\text{Ru}$ defects to form
in NaRuO$_2$, revealing a full solid-solution between NaRuO$_{2}$ and
disordered Na$_2$RuO$_3$. We report the synthesis of alloys along the
Na$_{3+x}$Ru$_{3-x}$O$_6$ solid solution and characterize changes in the bulk
magnetization and electron transport as a function of Na-loading. Our results
highlight the importance of stoichiometry control in NaRuO$_{2}$ when
investigating and interpreting this material's physical properties.
