I recently got one off a Gardener's Choice (Kmart in house brand) recently and it will bolt straight on to my Victa V40 Chonda.
The only problem with the existing starter is the pawls won't spread out enough when I pull the rope, despite having oiled it. is there more I can do to save chucking it in the bin?

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
