Hello everyone, I was given a 2006 model Snapper with a B&S quantum 6.5hp xrm engine with which a young kid had hit a rock or stump and the machine proceeded to scream when it ran. Rather than toss the mower I thought I would try and fix it cause I am in need of one. It appeared to me the shaft was warped so i dissassembled the machine and removed the shaft. My question is whether it is economically practical to try and replace this shaft (about $70 for shaft and shop manual) or just buy new mower or engine? If I did replace the shaft, will "timing" have to be set on the machine and would the manual tell how to do this? Could the shaft be straightened ? If I bought a new engine where would I find one(and how much) and could I replace it with a different make, say a Honda? Lots of questions I know but it appears from previous threads that you guys know Lawnmowers and I hate the thoughts of just trashing a 100lbs. of free lawnmower if it can be fixed. Not to mention I will still have to shell out $300-400 for a new mower. Thanks for any help.
