I was wondering if the pistons are locked, because I don't think they're moving. I checked when I was cleaning the Carburetor the second time. But, There isn't any resistance when I pull the cord. This is again, A Troy-Bilt Briggs and Stratton.
My other mower is a newer Briggs and Stratton and the only reason I find this lawnmower to be my best is because it is self-propelled, and my other one, which is quite nice, is not.I'm confused with some of the description. You say it won't budge but then you say there is no resistance on the pull cord. If you managed to get a spark, that tells me that the motor is turning. Also, you said "pistons" (plural) - the model number traces to a single cylinder engine. When you pulled the plug, was it wet after trying to start it.
If the motor isn't turning, you've probably seized it. If it turning very freely and you have no compression, you have likely either broken a ring or holed the piston.
If this is the nicest mower you have I'd hate to see the others.
You said that you cleaned the carburetor, often inexperienced hands, mess this up, by turning the metering screw too much, and basically shutting of the fuel flow.Okay, so I am very uneducated in what kind of engine it is. I thought that the engine had two pistons because I took off the front cover that hid what I assumed was the two pistons. But, what I meant by It wouldn't budge is that It wont start, make noise, sputter, anything.There is no resistance when I pull the cord, and It does spin the blades. I am getting a spark, and it has a new spark plug.
Yes, but the engine makes no noise, if there was a fuel problem, the engine would still make some noise, right?You said that you cleaned the carburetor, often inexperienced hands, mess this up, by turning the metering screw too much, and basically shutting of the fuel flow.
And they sometimes tighten the metering screw too much, then back it off.
This will ruin the carburetor, because the needle then reams the hole out and caused a permanent flooding situation.
If you have spark, and compression, then your problem lies in a poor fuel delivery.

Ok, so I forgot to mention, because I'm an idiot sometimes, the engine backfired when it died. And, I just checked if there was compression, and there was very little. The head came off and the things under the cover that says OHV weren't moving. Like I said, I'm very inexperienced and don't know if that's important or not. So. If its possible to get it fixed, should I do it myself or take it to a mechanic?
I probably just removed the engine shroud.Here is the illustrated parts manual for that engine:

It is indeed an OHV (valve-in-head) engine. On re-read, I tend to agree with Dexter - did you take the cylinder head off or just remove the engine shroud?
Okay. I looked at the illustrated parts manual, and I did wind up just removing the engine shroud. I am going to (tomorrow) remove the cylinder head. But. Are the valves supposed to move when I pull the cord?I probably just removed the engine shroud.

For now that you've just removed the cover that has OHV stamped into it. With the spark plug removed, slowly pull the rope to rotate the crank shaft and watch the 2 rocker levers that you see after removing the OHV cover. At the end of each lever there is a push rod that goes down into the engine to the cam shaft. If those 2 push rods and rocker levers do not move or if only 1 of the 2 moves you're done at this point. If both rocker levers move as the push rods move up and down, put a pencil in the plug hole and pull the rope. If the piston doesn't push pencil out and it doesn't go back in with a little pressure on the pencil for a complete revolution you're also done at this point.Okay.
