Welcome to the old bike world!
Pls don't be offended Kevin, you'll get all the help you need here, but I'm assuming from the naivete of your questions that when you say 'restoration' in your first post you must be referring to cosmetic, i.e. metalware restoration, rather than mechanical work.
Reference to the Owner's Manual would have told you that the 'E' position is for Emergency start - i.e. flat battery.
I'm 99% certain that the fact that you have an 'E' switch position confirms that you have an alternator with coil ignition, but your bike's a bit modern for mag an' dynamo Philistines like me.
I endorse completely the suggestion to visit to your local section were you can benefit in 20 mins from experience to correct basic, common, faults that would take days to diagnose/discuss on here.
For example, the carb flooding is probably because:
a) The needle isn't shutting off the supply when the bowl is full.
b) Gummy deposits from old fuel.
c) Dirt under needle.
d) Fibre washer where it shouldn't be.
e) Punctured float.......?
Have you included the carb in your 'restoration'?
Oil from the plug 'ole could be:
a)Plug needs tightening.
b)Faulty plug construction - even if it's a new one - ceramic not sealed to steel body.
c)Excess assembly oil (if you rebuilt th'engine) needs to be cleared from cylinder by running the engine 'for a while' to burn it away.
d)Th'oil may well have leaked out of the rocker cover and is merely collecting at the plug 'ole.
e) Copper washer missing from spark plug
f) All of the above, plus a good few more possibilities from someone who is more familar with Lightweight models than I am.
Hope that gives you somwhere to start.
