I had trouble starting my 58 today, I have already turned the carb around so that it points up in an iverted installation, the choke was working and closing after every fouth flip, and then it occured to me that when I switched on the ignition I could hear the 1 second burst from the plug, I took the plug out and drained the fuel in the cylinder a couple of times and could still hear the 1 second burst, so I took the cap off agian and noticed the inside of the plug cap was wet, dried it out with some tissue paper, put it back on and when switching on the ignition the 1 second burst was much more subdued and I got a kick out of the prop, obviously I was tracking the ignition to the cap, second flip and away it went, moral of the story is make sure your plug cap does not get fuel in it when you take the plug out.
