Today after work I took the motor out and pulled the pulley off and found a stepped crank, I thought all these small lawn tractors had 1" x 3" cranks on them. Turns out some of the early model Vert shaft engines had stepped cranks. 1" down to 7/8" (see pic) Live and Learn.
The engine has a Code# of 810326 11, Model# 252707
I think that makes it 1981yr made, which is what the tractor is, most likely original.
So now the hunt is on for another pulley off of a later model Briggs.
Or I have to modify the pulley I have.
The irony is that Eteks are suppose to have a 7/8" x 1-1/2" output shaft, but the one I got is 1" x 2-7/8"
I was so happy to get the 1" shaft thinking that it would be a simple swap.

You'll get it sorted out.
I know, you're a resourceful guy.

Can you bore the pulley you have all the way thru to 1 inch and then just use the key to where it fits?
Looks like they used a piece of 1-1/4 outside dia pipe and put a bushing in it at one end to fit the crank.
The 7/8" stepped part of the crank is only 1-1/4" long.
I can probably knock the pulley bushing out, then I'd have to put another bushing in to fit the 1" Eteks shaft.
The inside dia of the pulley is 1.060"

If 1 goes out the back then 3 are under the hood, 1 battery probably weighs the same as the gas engine fuel tank and fuel.
Doug, with most of the 270 lbs of batteries up front, will you need to do anything to the front axel / pivot?
So only the weight of 2 batteries, 135lbs will be added on the front end.

Thanks for the info the pulley assembly is
5" tall, bottom one is 5-3/4 dia, top one is 4-1/8 dia.
Anybody got one kicking around.

Says he has 30 of them total from different lawn tractors.
Hopefully this problem is solved.

It's good to get rid of stuff you don't need for stuff that you do need.

Glad to hear that you made a good trade. So will you be bolting the motor on this afternoon?
Im pleased to hear you have that worked out. I was thinking the same as Casey... whens it going together?
Next thing to do is make the mounting plate.
