Riding Motor Since 1950
Well I dug into the solenoid last night to replace the contacts with the ones from the 1.4kw starter assy listed on the first page sourced from discountstarterandalternator.com.
The contact for the motor lead is NOT compatible.
I would recommend buying the rebuild kit for $20.
The OEM contact is asymmetrical, while the contact on the replacement starter is symmetric. See pics.
I cleaned and lightly sanded the worn areas and figure everything will work better for a good while.
**Edit: I ended up filing the contacts down to a nice CLEAN surface area before my kit came in. I've had perfect operation for almost 3 weeks now**
