Walk behind MTD YardMan Walkbehind mower 12AE999M401

[mowerdad69]

I have a MTD YardMan 21 inch walk behind mower. 12AE999M401 model, electric start.
I need a cast motor shaft hub. Does any one has a good used one to sell? Also need a wiring diagram for this model of mower.
Are the electric start packs serviceable?
Thanks,
mowerdad

Thanks for the reply. I will purchase new.
Today, I was able to do some wrenching and cleaning of my new to me MTD YardMan Walk behind mower. The mower now starts with the key. :thumbsup:
I reset the magneto gap, maybe that helped.
