8 HP Briggs engine just spinning

I own an older snapper mower with an 8 HP Briggs engine.

When I crank the engine, it just spins with the mower not turning over.

Any ideas as to what is up?

Video link attached.

I can't watch the video either but if the starter is spinning real fast but the motor does not, sounds like the Bendix on the end of the starter is sticking (not being slung up into the flywheel) or the gear is just stripped out.

Some describe "not turning over" to mean Not firing up [starting]...A misnomer....But, If that is your case, and eng is spinning fast...you lost compression....Then you will need to remove the spark plug and verify if the piston is moving when cranked...! Hopefully, it is as jseabolt mentions...

as others mention, you need to clarify the description of what is or isnt turning vs stripped starter gear or starter bendix just isnt kicking the gear into the flywheel.

is it the old style engines or is it the OHV type?

You can only learn if you ask the question, so there are no dumb questions.

Your YouTube video is private, so we can't watch it.
