You said it acted like it siezed, and now it turns over.
2 strokes are prone to exactly that.
They sieze up trashing the rings but can still turn over right after.
How does the cyclinder wall look?
Smear marks on the exhaust side?
Run a compression check on it .
Also look thru the exhaust port and look for a scoured piston , that's where the damage starts when they lean out .
It wont be worth fixing if it needs a new cylinder/piston. Craftsman handheld equipment are usually throw aways when they seize up . You can just buy a replacement so cheap.
