I don't doubt he gave me a good answer... for someone who wants to do a rebuild. It's not something i care to undertake, so it's kinda an answer to a question i didn't ask is all.
But again, i appreciate the effort that you fine technically talented people have taken.
I can order on amazon for $25 canadian to my door in one day. Bolt it on and if it doesn't work, then try to rebuild the old one i guess. Potentially return the old one. I was afraid that perhaps mounting holes and openings might not match up if models were wrong. But sounds like they mostly all fit different applications i guess.
Just not sure I have the time, patience, products and tools for the rebuild. I don't need the mower to run like a ferrari. For $25 and very little effort, i can switch to plan b if no good.
