Is the plug not firing? Can you check to see that it's actually firing at the tip? There are YouTube videos to show you how. Swap the two plugs to see if it is still a problem. If it is it you can rule out a bad plug. Do you have good compression? If the plugs are firing every time, then you may have a stuck valve or a problem with getting fuel into the cylinder.

sounds like you have a broken valve, you need to take it in and have a new valve put in, check compression you will get different readings, anyway needs to be taken in and have a professional look at it

Did you check for spark of assume that since the spark plug was not dirty that it is not firing. I am leaning toward water in the gas since you have to keep the choke on and it is blowing white smoke. You may want to drain the fuel tank and carburator and put in fresh gas. Good luck!
