You may have a few little things to line up, but as has been said the pulley placement is your main concern. 
 

There are plenty of brands of engine that will work. Of course some are better than others. That’s just a decision you’ll have to make.

Thanks so much everyone, I appreciate the guidance!

I can't say that I am surprised, but the more I dig in, the more I realize that I need to dig in more.  While the transmission shifts freely, I discovered the brake was frozen and the main top pulley was in pretty bad shape so out it came.  I stripped my first rusted bolt while removing the caliper (documentation is pretty fuzzy so not 100% sure that's what it's called), probably won't be the last.  To my surprise I found a worm in it!  LOL!

 

 

I have no clue how the brake works, and found some replacement pads at A-Z Tractor but can't figure out if they'll work... part of tomorrow's learning.

 

Current state for the poor old guy, hoping I can save him!

CALL  📞   ☎️   Lincoln at A to Z.  

 

He's pretty knowledgeable about tractor-ology in general. 

Good guy. 

 

He may even have some additional insights for your model.

As long as you can line up the belt and it fits under the hood, anything is possible. We'll help you as needed.

 

OK... it's needed.  LOL!  I found a few possible replacement engines, ones I've zeroed in on are a Briggs and Stratton 28D707 and a Kawasaki FB460V.  Here is where I'm stumped.  Both have a 1" x 3.15" long shaft according to my research.  The Tecumseh that came with the machine has a shaft length of approximately 4.5", but the pulley that I really care about (the top one) has a 1.75" drop (picture posted earlier).  Could a pulley be installed at specific height on a new engine or do I need to be looking for an engine that has a shaft length of 4.5" so I can remove the pulley pair from the Tecumseh (upper belt and lower belt) and install it on a new engine?   Hope that makes sense, thanks in advance!

You’ll be hard pressed to find an engine shaft 4 inches long nowadays. Just over 3 is more common. But, you can use spacers to set  the pulley that goes to the transmission on the 3 inch shaft. 
 

Also- vertical engines often use a welded collar with both pulleys that is held in place by a bolt into the end of the engine shaft. Finding a comparable replacement shouldn’t be impossible.

If you don't plan to use the mower deck the lower pulley can hang below the end of the crankshaft without any problem.

[shaggydoink 34]

Thanks guys.  I'm still a little fuzzy on exactly HOW this will work, but knowing that one of these replacement engines CAN work is exactly what I was trying to determine as step one, so mission accomplished!  I appreciate the ongoing help.

As I thought about things, it occurred to me that if I bought just an engine for $50-100 that I'd still be missing a number of needed parts like a fuel tank, fuel pump, ignition and seat all of which together might start adding up cost-wise.  I found someone selling a newer model Craftsman for $70 on Facebook Marketplace, did some quick research and took a gamble that it'll do the trick... if not, I may already have a second project on my hands!  LOL!

 

 

[shaggydoink 34]

Well, I knew this was going to be a learning experience... it didn't even occur to me to check the dimensions of the engine on the T100, turns out it measures 11.5" from the shaft center to the front edge, whereas the A-100 only has room for 8.5" (maybe 9" max).  Oops!  I'm not overly concerned, my wife actually took a liking to it when she saw it so maybe it too will get some life breathed back into it one day.  Back to Facebook Marketplace I go, this time a smidge wiser.

Hey, the tires are worth more than that!

[Sailman 1,288]

Just a thought on the rims. I had some front rims with holes and pin holes, rotted tires setting outside...

I cleaned the rims as best I could with wire wheel and die grinder (get rid of any sharp edges). Used epoxy and fiberglass over the larger holes and coated thickened epoxy over pin holes. Painted them and put tires with tubes on them and have had great success keeping them in service.

[shaggydoink 34]

I've got a line on two other possible donor machines, one has a 12.5HP Briggs and Stratton, the other has 15HP Kohler.  Both are $80, hopefully I'll end up with one of them and not BOTH of them, but we'll see.  I fussed with the Craftsman T100 for a bit and got it running, so what I don't keep I figure I can sell.

 

In the meantime, I spent some time researching and ordering the parts I'll need for the A-100.  Tires, tie rods, brake pads, tail light lens, headlight lens, shift knob and decal set... underwater on the investment vs. value I'm sure, but I'm determined to save this poor little guy.  I also spend some time cleaning up parts.  I need to finish off the nooks and crannies, but the transmission is getting there as are the rims... a few pictures below.

 

I was going back and forth on whether I want to do a complete re-paint or clean up and capture the current patina.  The hood has a big chunk cut out on one side for some unknown reason, so I'm thinking I'll have to go the complete re-paint round... which means more tear down... feeling a little like Alice in the rabbit hole!  LOL!

Nice deep dive!!!
