I don't know what the parts availability and cost is for mower parts. I am out of state for business, I got a call saying my rider is not working. Its a '94 Yard Machine that I picked up for cheap last summer (so its nothing special). Turns out not working = broke rod and scored the crank. I have to find out if the cyl got scored as well, my fiance couldn't remember exactly what the guy said who looket at it (crazy friend of the family). So what is the cost effective thing to do? Replace the crank & rod, try a machine shop to repair the crank, find a different motor, or just start looking for a different mower?
