If that choke is missing then i would remove the choke needle and see if its even there! Might just be a dummy nut!
Too much gas flow the 220 will not start, the needle has to seat to stop the flow if its wide open then your not going anywhere. Since the motor is in non working condition i am sure someone before you played with the carb to see if it affected anything.
Starter motor does it click when you press the start button? There is a solenoid next to the battery its is round with a 20amp fuse(under the connector cover of the solenoid) if it does not make a noise this is your problem. If the battery is low it can make a buzzing noise when pushed, not enough amps to get starter going and don't continue to do it you will over heat solenoid and possible pop the fuse.
Ok one last recommendation to you before you torch it.
One since you have another 220 try another Cdi box its mounted to the left side of the airbox. This can cause erratic timing if bad or limiting of rpm or just no start. Maybe its not the engine blowing but pre-ignition of some sort.
*Read whole thing before you start
*Before you do this take pictures of it mounted and the inside of it with a camera just encase you forget something or have to order parts you remember how things go back.
If that doesn't work the very last thing i would do, (since even with a new or used engine the carb has to work correctly) is remove the carb. which if you unscrew the bracket at the back of the carb. and the bracket at the air box and remove 2 10mm screws you can remove the airbox and get access to carb a little easier. When you get it out make sure you check the choke needle, its small and brass if non existent get one. Also check the accelerator needle, this is plastic with a long needle. Then remove the bottom of the bowl 4 screws and make sure its clean if not clean it carb cleaner scotch brite whatever works just don't damage the seal. Then if you push the pin that holds 2 black floats by getting a pin and pushing or most times just putting the carb on its side, the needle which cuts gas flow should come up with it. The needle should have a rubber head make sure its free of debri and in nice shape no tears or odd ends, if not clean it or replace part (Compressed air works well for passages). Then remove the main jet(should have an O-ring at the base of it),(tallest one in there) use a big flat screwdriver and remove it. Check the tip for debri, and poke a wire make sure its clean. Then remove the pilot jet right below that one, its a smaller screw driver. Do the same to that and clean it.
ok now check the holes in the carb. make sure there free of debri where the jets sit. A wire should poke through from the bowl side to the air side.
Last thing would be to check the knobs and make sure somebody didn't mess with them. One is the idle knob big brass knurled knob on the left side of the carb(front position being in relation to mounted to engine) you can turn this with your fingers, remove it and clean tip and check for debri then just screw it all the way in turning clock wise and 2 full turns counter clockwise when it starts you can readjust this easily if low or high RPM. Now look at the small brass screw towards the front of the carb. it actually stick past the fuel bowl if needed put fuel bowl on and look for a brass screw. Same with this remove it and check for debri then screw it all the way in and then 1.5 turns out. This should be a base setting for your carb. From this point put carb back together and install JUST the fuel line and unscrew the little brass screw on the left side of the fuel bowl its there to remove dirt from bowl but this way you can see if the gas flows. As its unscrewed, turn the gas to reserve or on and see if it flows out of the hole at the bottom of the bowl next to the screw, if so then its filling the carb and your ok to close it. Once closed make sure that after 30 sec or so you do not see any other tube leaking. This would be the float needle not properly closing.
In which you did something wrong and you would remove the bowl again and check.
If everything ok put carb and everything back and try and fire it up.
*PS don't over tight screws or jets once there's resistance give it just a little turn, especially the bowl or else you will find you broke the gasket and have to buy a kit.
* Also if the seal gets stuck when removing the bowl use a sharp knife and gently help it peel away.
