I am looking for a replacement engine or mower. The 200 series Toros weren't the heaviest duty but we've got 20 years out of it for $2400. It is in pretty good condition other than the seat and the engine at the moment. I was told the Mitsubishi L3E Toro blocks were proprietary and other L3E blocks might not be a drop in.
There is a Toro L3E about 4 or 5 hours away for $1.000. I'd have to do a compression test before buying.
With a new head or block not available, I don't see many options if I have cracks instead of a head gasket issue.
I'm wide open to suggestions
