I have this Chonda that needs a new starter. Is a grey mower with a mostly black engine with the words "4 stroke, overhead valve, OHV400" in the centre of the starter. No ID at all but there used to be a sticker on it that may have said Sanli.
The starter looks like the 4 bolt sanli starter in the catalogue. It looks good enough for me but someone with a Sanli might know what their statrer looks like.
The current starter catches somewhere and jams. Easier to replace I think at the advertised price.
