Hit a stump with my John Deere JS -63 walk behind, B&S Intek engine Model 121602 0529. Crankshaft is now bent; mower is approx 2 years old. This is just my backup mower with over 300hrs, need an affordable replacement engine. The B&S replacement engine catalog does not list my 0529 model number http://www.briggsandstratton.com/miscpdfs/RNT/EngineReplacement.pdf The parts list from Briggs (IPL Form Number - MS2143 ) lists that the crankshaft on my 0529 model is also used on 0525 and the 0349 model. My question is how reliable are those IPL lists from B&S? Is it a fairly save bet that when I order a 0349 model, this thing will fit?
