OK, I won't ask about your high tension wire repair in case I don't think it will last. It sounds as if you had already fitted a Magnetron ignition unit.
If your spark plug is wet, despite having spark, your mixture is probably very rich. Do you remember when I told you that with your model of carburetor, if you have a bowed tank-top, and you put it together without the little teflon washer, it will be extremely rich? And you couldn't find the invisible washer, so you denied there was ever one in there, despite there being a pin that was only there to hold the washer in position? Do you see a pattern forming in all this?
Unless someone had fitted the 391413 kit, then later found it wasn't needed and just left the roll pin in place without the washer (a very unlikely chain of events, in my opinion) your engine has a bowed fuel tank top or carburetor bottom, and is flooding because it no longer has a teflon washer, because you lost it. If it makes you feel any better, the only time I ever took apart an engine that had the kit in it, I lost the washer too, and the engine flooded when I put it back together. I do not like that kit, so I draw-filed the top of the fuel tank flat, and it worked perfectly ever afterwards.
