After hitting a rock, my Craftsman mower backfires when I pull the cord, won't start.Should I toss it?

Model 917.388541 B&S 5.5hp 21" Rear discharge 5 yrs old ran fine til I hit the rock. I restarted several times with difficulty, then it started backfiring when I pulled the cord, and it won't start at all now. Do you think it's totaled?

More than likely when you hit the rock it bent the crankshaft. If the crankshaft is bent, it's generally just not cost effective to make the repair unless you know how to do the job yourself. The part is somewhat reasonable, but the labor is where you'll start digging into the bank account pretty hard. If the machine is about 5 years old, it will more than likely be in your best interest to just replace it.

You could replace the engine but then you'd still have a semi-old machine with a new engine. Or you could fix the engine and you'd have a semi-old machine with a brand new crankshaft.

In most cases it's just not cost effective to fix it either way unless the cost for a new machine is going to run you more than $500
