Have tried all internet . Can not fine a drive pulley for my 443877 Sears rising mower's engine. The engine calls for a 1 1/8"shaft pulley. Any ideas?

Let's start with the mower's full model number from the serial number tag. That we can look up the mower. Hopefully it is a riding mower and no a rising mower.

That’s not the full model number. I also see you’ve posted three threads about the same issue, that’s a NO NO. If your model number is 917276683. I think think the part number is 586478501. Recheck your model number.

Something is just not right as there is no Briggs 443877 engine.

445677-0413-E1 that the 917.276683 claims to have has a one inch PTO.​

Just post the image of the serial tag and see if obtain at the mower model number.

This is shaping up to be a used engine refit with a larger crank diameter.
If that is the case then the OP has a problem as I haven't seen a double stack pulley that is 1-1/8 ID. And I just had a problem with CC ZTR where customer went out and got an engine with a 1-1/8 crankshaft to replace his current engine. The problem CC didn't make drive pulley that was 1-1/8 id for that mower series per CC tech support.

But first we got to get good valid equipment numbers and not some off the wall numbers. As the numbers that the OP posted are invalid. He might even have an electric PTO setup with a separate drive pulley; who knows.
