One key point: if you ever try to operate that engine without the air cleaner fitted, it is essential to put the air cleaner retaining screw into the carburetor, or it will flood to an epic extent - probably won't start, but if it does it will fill the area with black petrol smoke.
Now that you've adjusted the speed control cable correctly, the kill switch should work unless something is damaged somewhere.
The long series of numbers stamped on the cooling air cowl above the muffler are in three groups: Model, Type, and Code. The model and type describe the engine, so you can find parts and manuals for it. The code gives the date of manufacture and the plant/production line where the engine was made. The first two digits in the code are the last two digits of the year of manufacture: e.g., 85 would mean 1985. The second two digits are the month of manufacture, e.g. 07 would mean July. The third two digits are the day of the month, e.g. 25 would be the 25th day, so in this hypothetical example the engine would have been made on 25 July 1985. There are two more digits after the six that reveal the date of manufacture - the production line and plant codes. I don't know how to decipher those.
