Hi guys. We just moved into a new house and I mowed the lawn for the first time. Just before cutting the last section, there was a small piece of rebar sticking up under a small patch of dirt, which was not visible until I hit it of course. This caused the mower to make a knocking noise. There are no cracks on the outside of the motor, but I feared a rod may have been bent. I took the blade off (which is now damaged) and started it up without the blade. The mower runs without any knocking noise this time but, it feels like it has less power. So I bought a new blade, attached it, and started it up. The knocking returned again.
If I had a bent rod, wouldn't the knocking noise be there regardless of the blade being attached? I've recently replaced the part pictured below as that was knocking in the past due to the key being sheared off but, after inspection, it's still intact. If this doesn't sound like a rod issue, what are some other possibilities? I believe my father has the tool to do a compression test. Not sure if its for a car or a mower but, I'll check it out and at least try that. Thanks in advance
