B&S seized 5.0 on push mower

[Safehorses]

Oh and welcome to the forum.

Thank you!

i'd be spraying a couple squirts of penetrating oil thru the spark plug hole down the cylinder walls because it sounds like the piston rings were rusted to the cylinder. Running that without some lubrication will only tear up the rings.

I'll do that. Thank you.

If you try putting oil in the cylinder do it very sparingly. Now that it is free really don’t need to, as the engine oil will start doing its job. To much oil at this point will not allow the plug to fire.

OK thank you.

Because you were able to free it up using a block of wood and hammer, I suspect that the rings are fine and that the rod was probably frozen on the crankshaft. If you get it running I suggest you change the oil after 2 hours use to remove any debris in the oil. No need to put any oil in the cylinder, just my opinion.

The hammer and wood worked! It's free! I'm so excited. Thank you all so very much!
I'll have to run out and get fresh gas and see if it will try to start.

Glad you got it to rotate. Keep an eye on the oil level after you run it.

Sounds to me that the mower was run without oil. After it seized the user put in fresh oil to hide their mistake. Sometimes these units can be saved, but your odds are 50/50. If you want to give it a try, this is what I would do. You really have nothing to lose.
1. Remove the spark plug.
2. Tip the mower on its side, carb/air filter up.
3. With gloves on try to turn the blade backwards, meaning you are pushing again the sharp edge.
4. If this doesn’t move it, take a block of wood against the cutting edge and give it a few good whacks with the biggest hammer you have. If it is not seized too bad it should free up.
5. If you can’t get it to move you are out of luck, junk.
6. If you free it up and it moves freely, tip the mower back up and pull the recoil a dozen times, no plug.
7. Install the spark plug and see if it starts.

Check to see if the handle bars are extended My son got a mower and the handle bars were not and the blade was hitting againbt them so he couldn't pull the rope

I have no idea the last time it was started. No idea if any maintenance was done to it. It's a older mower but looks almost new.
I picked it up last Fall. Checked the oil, put gas in it and tried to pull the cord. Couldn't pull the cord at all. Disnt want to break it so i emptied the gas out put it up and here I am.
You guys are great! Thank goodness for forums and you people helping dummies like me.

You aint so dumb you knew where to go to get the answer to your question and a solution to your problem.
