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.
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.
I found this. must have read mdl wrong. Briggs & Stratton 44S977-0033-G1 Vertical Professional Series Engine, 25.0 Gross HP, 724cc, 1-1/8" x 4-19/64" Crankshaft, 1/4" Keyway, 7/16"-20 Drilled & Tapped, Remote Controls, Fuel Pump, 12 Volt Gear Drive ReadyStart with 16 Amp DC Alternator, Replaces 44S877-0001-G1, 44Q777-3136-G5 and 44Q777-0136-G1
Apparently you want to keep us in the dark about your equipment. We need valid numbers from the equipment to know what you have. So since you think it is not necessary I am stepping of this thread as I got more important things to do than to guess at what you have. Its your baby now.
BTW this is for increasing the crankshaft OD size to fit a larger ID pulley, not to reduce the crankshaft OD size to fit a smaller ID pulley. And that particular adapter also extends the length of the crankshaft PTO end.
You are most likely SOL finding a 1 1/8 dia stack pulley.
Most generally when someone needs such they have replaced a 1 inch shaft engine with a 1 1/8 shaft engine. Experience is what you get when what you got is not what you wanted.
I will survive, do not worry. A pulley is in progress...I found that the pipe used along chain link fencing is 1-1X8" id, and that was the breakthrough! Thanks for all your replies.
I will give the old "college try"... and if impossible, I will have the shaft machine tooled and welded to the pulleys, professionally. Thanks for the response.
I have genuine 1-1/8 V-belt drive pulley from Craftsman rider if you are interested. It has the crank key made into it.

When this cat decides to post valid equipment numbers then we know what he got for a mower. I manage to figure that he has a 44S877 instead of a 443877.
IF he just post a picture of the mower's serial tag it would help some. Meanwhile ICE has deported my crystal ball for telling the truth on them.
This is a single belt drive pulley with a 1.25" tube extension on top and bottom (As measured from the pulley edge across to center tube) One tube section has a 1/4" keyed area formed into it. It is intended to be used with an electric PTO clutch below it. This one came off of a Craftsman DGS6500 garden tractor. Number shows to be 194343 but was substituted out later.
