A few years back I was given a Lawn Boy 10247 with the duraforce 6.5 hp. The deck felt solid but the engine would not budge. After taking it apart, I am fairly sure the engine did not lock up from no oil as everything was coated in a oily/greasy mess, however all the bearings were seized up and rusty as were the piston rings as if water had been in the engine for a while. The cylinder liner has a bit of rust as well. The crankshaft has very light grooves imprinted in the journal from rust. I priced out the parts for the rebuild and I quickly got to $300 and new it wasn't looking good for this project. Am I missing something, or am I just looking in the wrong place for parts? I basically need the entire short block, but not interested in spending $300 on an old mower just for the sake of having a 2 cycle. This would just be a back up mower/project mower, so I am in no way in desperate need for this to work again. I've read a few forums where guys found short blocks, but I have not found any online that are still available. What would you guys do???
