Don't understand why would you repair. You have a 200 dollar mower and it is going to cost 200 dollars to fix. Now you have a old worn out repaired 200 dollar mower. why not have a new 200 dollar mower. Now lets keep dollar for dollar and same mowers. When someone brings me a repair job like that I refuse to work on it. There is a time to stop unless you are into restoring old mowers for a hobby.
I'm with reynoldston on this one. A $200 repair bill on a $200 lawnmower has got to be at least a complete engine rebuild. If you maintained your mower and this still happened, I'd look for a different mower.
A friend brought me an almost new Honda Pressure washer. Tried my best on it, couldn't get it to run. Put my hand over the exhaust when I pulled the cord a few time, no puff or anything.
Unscrewed the 4 screws that cover the OHC, saw a chain and what looked like bits of pepper that had just gone through a grinder... It was a plastic gear.... on a pressure washer...
I reuse the frames on them for hauling things like my 4000 watt generator around that must be 30 years old. I even have a homebuilt compressor that haul around on one of those frames.
I kept the pump off the pressure washer as they're usually at least $200 for a new one.. will I ever find a pressure washer that needs that pump?? Who knows.. Kinda hard to toss it though.
If you called me about that mower, I'd usually offer a very small amount to take it off your hands. I'd put another motor on the deck IF the deck was in decent shape.
But yeah, if you told me it had something wrong that the repair guy estimated a $200 repair bill, I could probably do it for a lot less but, then again, I'll have maybe $100 in a mower I can't get $100 out of.
Find on on CL that has a decent motor and a rotten deck, and swap them motor if that's the issue..
