If so, I'm apt to think you have a solenoid issue. Is it clicking in?

I wouldn't worry about the battery being big enough, so long as it has a good charge.
However, these engines have a rather cheap plastic bendex drive.
It is prone to braking apart and jamming the flywheel.
If jumping the starter doesn't produce the desired result,
You will have to remove all those sheet metal covers.
It's not really a big job.
First you can pull the spark plugs and see if you can spin the engine over by hand.
One or two hands on the screen on top of the engine should do.
The bendex drive is cheap enough. About 10 or 15 bucks here in the US!
Good luck and keep us posted!

As Joe said the bendix can be replaced fairly cheaply ad easily. B&S used a couple of different bendix styles so you may need to take the starter to the parts store with you.

Did you jump wire directly to the starter?

Yes, i did just have the starter wire onto the battery, bypassing the solenoid. I believe it is a bendix gear motor, but when i connect it up to the battery the gear does not shoot up to engage with the flywheel or do anything it is just motionless and it doesn't make a straining sound as if it were trying. And yes the engine is free and not jammed .
Thanks

Pull the starter off the engine and bench test it.
Put it in a vise and jump it same as you did on the engine.
Or, just put it on the ground under your foot and jump it.
If it does not spin. Take the two small bolts of the ends.
And disassemble it. Sometimes a good cleaning will get it to work.
Inspect the wires for a break. Inspect the brushes for excessive wear.

It spins in reverse and the bender drive will not engage.
You want positive to starter negative to ground.
