  We construct SU(2)^2xU(1)-invariant G_2-instantons on the asymptotically
conical limit of the C7 family of G_2-metrics. The construction uses a
dynamical systems approach involving perturbations of an abelian solution and a
solution on the G_2-cone. From this we obtain a 1-parameter family of invariant
instantons with gauge group SU(2) and bounded curvature.
