1200 Run again or parts???

[Maple Cabin]

Newbie and first post.
Picked up this last week for $150 CAN
Sat for years outside, carb in a box, clutch frozen, head light casting broken, deck ok (one wheel welded back on, no holes)
Remove and flipped the deck and the blades are all most new but very rusty, impact and the nuts are free, sharpened the blades reinstalled, remove top cover, had to press the tension pulley pivot from the shoulder bolt. Got done with very little damage. The L&S is the deck is good and smooth after about 20 shots of grease into each bearing. A little test cut and all good.
Now on to the next.
Only one engine bolt to the ISO mounts??? Had to pull engine to get at the clutch did not want to try the engine with the clutch and shaft like that. So got the clutch out, freed and faced the plates. Back in for now.
Engine: (All tin removed) strapped it down to the frame, inspected the carb looked ok other than a bent Idle jet (found a spare) Set to 1.5 turns. Added 8“fuel line (that’s my tank if things go bad). Connected wires to start and run. Put battery in the back. Turned the key. Cranked 10 seconds and fired but quit. Half choke and fired right up. “Looking like a runner”
Some pictures if I can download. ISO mounts reuse???
The washer with the 4 bolts is cause the flex plate has many cracks. Only temp if its a runner.

Thanks for the looonnnggg post.
