The engine that you used is is the one I would have prefered, however the toro is cheap and I had several laying around. Funny thing is I picked up the engines cheap just to get the diaphram carbs.
Yes I just put the whole engine (less the shroud) in the lathe. That made it quick & simple. Then clamped the output shaft in the chuck and milled the keyway. Never had to disassemble the engine.
I like the 2 cycle engines for thier weight & rpms, of course I have to live with the loud exhaust. The input manifold on this engine is all metal.

Nice! I built a bike with a 4/5hp 2 stroke Tecumseh engine, it was from a lawnmower but the same block is also used in snowblowers. View attachment 55473View attachment 55474
The second pic is how it would look in a blower, maybe you've seen them before.
Pretty beastly engine (140cc), it really hauls on my bike, but the instant it develops even the slightest of air leaks there is a giant crankcase explosion/intake backfire (causing the carb and Bakelite intake elbow to go flying off the engine). The intake is all o-rings too, so I have to glue everything shut with gasket maker to prevent leaks.
How did you turn down the crank while still in the engine? Did you put the crank in a lathe and let it spin inside the engine (engine just riding on the shaft)? When I had to turn down my shaft to get a pulley on I ran a coarse file up against the shaft while the engine idled. Which turned out to be a horrible idea because the shaft wore down faster where the keyway was (less material to take away).
