Husqvarna LT112 briggs&stratton 12hp won´t start

I couraged myself to seal the crack. After that I will be topping the oil and having the test.

Something is probaply broken inside the engine but the sealing is pretty small job. Best scenario would be to get a little more lifetime to this engine.. maybe disasembly to the engine in winter or getting a replacement then.

When there is a hole in the block made by something on the inside of the engine, just sealing the hole won't do it......it's probably toast!

Did you check for piston movement?

You are most probably right

Did you check for piston movement?

I did not yet, how would I to do that?

To see if the piston is moving, take out spark plug, stick a long pencil down the spark plug hole until you feel it bottom out,while holding the pencil the whole time, then slowly spin engine by hand, you should feel the piston rise and lower.....if it's all connected the way it's supposed to be!

I did this and the the piston is rising and lowering. I also managed to put it on video.

I am now recharcing the battery, refilled some fresh gas and topped the engine with oil. Wish me luck.

Sounds like i can hear the piston rising in the bore,
Hope it works out good for you, but don't be surprised if you hear some clackity clack

That video doesn't look like a piston going up & down in a cylinder, that looks like a valve opening & closing on a Flathead type engine.

So no luck starting the engine. Soon giving up with this engine but I am not done quite yet.

One final try if someone could give a hand here. Shouldn´t it give some sign of life if the sparking and fuel injection would work? Any ways to ensure these are working? Start motor works and tries to crank engine on.

No...there is A LOT more to it than that. It might be out of reach for you.
