cratsman gt5000 engine trouble b&s

i have a craftsman gt5000 22hp b&s model 917.275972 and when running it i lost power then heard a cling from the engine and it shut off. It will turn over but not start. Getting spark and fuel. The fly wheel is very easy to turn by hand and is turning the wheels when in gear. Could the fly wheel pin be sheared or any suggestions please. Thanks for any help.

Kind of sounds like the engine blew. I'm guessing it's pretty low on oil?

The flywheel being easy to turn by hand is an indication there is no compression within either of the two cylinders unless the spark plugs were removed to check rotation.

Spark were in when i checked. Looked at push rods and they look good. As far as oil level, changed it 2 weeks ago and when it went down I looked and it had a small amount of smoke coming out of dip stick but oil level was good. Can it be saved. Thanks to both

The plugs were in. Even when it turns over you can tell by the sound there is no compression. Any advice? The push rods look good by the way.

Verify that the pistons are not moving, and if not, disassembly will tell the extent of the damage.

It doesn't need to come off for inspection. The engine needs to come off and the bottom cover removed.

Check the block for cracks, the piston skirts for damage, the camshaft for impacts and to be sure it's straight. I'd also think the crankshaft may have aluminum transferred on to it. Usually broken rods are from lack of oil, there is likely other damage that needs attention. Is there any aluminum marks on the rod journals on the crankshaft?
