Ok, I have a Honda HRR2166VKA walk behind lawn mower.

About a week ago, we had to have our septic tank pumped and serviced. Goofy-Eyes McGee septic tank pumper must have kicked a rock in my yard which wasn’t there previously. I ran over the rock and absolutely screwed my mower.

After I ran it over, my mower began vibrating violently. The blade was gouged pretty badly. I filed down the blade thinking it was just out of balance, but the mower continue to vibrate violently. I purchased a brand new blade, installed it, and the vibrating continued.

After doing some research, I realized that I had a bent crankshaft. I purchased a brand new crankshaft online and have spent the past two days installing it.

I used liquid gasket to seal the upper and lower portions of the engine housing together and let it sit for 24 hours before I put fluids back in it. After the 24 hours passed, I put fluids back in, cranked it, it started immediately and ran for about 8 to 10 seconds.

It has not started since.

Any help would be greatly appreciated.


ETA: 7/16

Piston it pumping, the lawnmower is drawing a spark, but not starting. Brand new spark plug.

You did something to mess up the Auto choke feature.

This is the OT. There is staff for that. We won't even discuss the septic tank.

Sounds like you hit some connection on the choke or the fuel feed. Undo the spark plug and see if its wet after cranking.

If you weren't such a dick to me in the past, I'd tell you how to fix it.

How much do you think that $350 mower has set you back if you bill your time out?

I would want to check the shear key -if may have been damaged when you hit the rock.

Tell me more. I’m actually thinking it has something to do with this or timing.

There are 2. One in the shaft underneath where the blade mount connects and one under the flywheel. Both are perfectly intact

That wasn’t smart. This could be your issue. Anything like that that gets into the engine can gum it up. Burn out rings, clog valves, etc. you have to be really careful that stuff doesn’t get into the actual engine itself.

I was pretty careful. It had permatex there before. When I pulled the engine apart, I cleaned it all up and reapplied new gasket before bolting. I let it dry for almost 24h. Shouldn’t have been a problem.

I have a very similar model. Check the tension on the cable to the kill switch. Cables stretch over time and with any manhandling. If you can, at the same time, pull on the cable (even with the kill lever held down) and give it a go. That would rule out the most simple explanation.

Permatex didn't do this in 8-10 seconds.

I know this is too simple but your gas is "on", yes?

That’s actually a great question. The gas is “on.”
