That happened to me a couple years ago. Total cost of a complete rebuild was $2200. Never again. If something major happens in the future, the generator will be nothing more than a boat anchor.
Otherwise, the GENERAC has worked just fine...and when Sandy hit, our house power went off for 4 days. The generator kept things going on a somewhat limited basis, but we had TV,and the fridge and freezer were just fine.
The thing ran for over 90 hours non-stop. Thanks for the 75 gallon gas tank!
If you find any info about a similar replacement....PM me. I'd like to know.
