I've got a Murray lawn tractor with a Briggs and Stratton engine in it.
Being a dumbass, I managed to run it out of oil (I think what happened
was I filled it with high viscosity oil by accident and that burned up
much faster than the other stuff in this hot weather).
Anyway the engine seized and I managed to get it loosened by turning
the blades so that the flywheel now spins freely. However the dang
thing still won't start up. First, it started to spin on the start and
hit something (clang) and stopped. I fooled around with it a little
and now the flywheel spins with nothing blocking it. Only problem is
it still isn't catching. Should I try some starter fluid in the air

That is supposed to happen if you hit sometime with the blade.....so you
don't snap the

I had a chance to work on a siezed up engine, last year. Please share my
Remove the spark plug, and squirt a bunch (couple squirts) of two cycle "gas
mix" oil into the cylinder. Then leave the spark plug out, and spin the
starter for a second or two. This should re-oil the walls of the cylinder.
I didn't do this. The motor (10 HP Tecumseh on a generator) started right u

item in less than a second. I also said some bad words.
It probably wouldn't have mattered a whit if you had...the seizure more
than likely overstressed the connecting rod anyway and it was
As noted before, I'm wagering it was the end falling off after the
"clang" that freed it up for OP...
