I've only had my 8N for a couple of years now, and once I figured it out it would start perfectly in about 1 or 2 cranks, hot or cold. Now for the last couple of weeks not so much. I tries to start after about 5 or 6 cranks, then about 1 cylinder at a time, of course when that 1 cylinder fires it disengages the starter and I have to try again, again same thing, then 2 cylinders will fire, starter disengages, same thing, then 3 cylinders, on three cylinders it kinds stays running until the 4th kicks in and then it runs like a champ, no flat spots thru out its throttle. I really haven't touched anything, except put on a governor that I rebuilt but that was last year, but it ran good after that. I've put in new plugs as soon as I got it, and also rewired it with new resister and everything was running good after that, the plugs don't have that much time on them .025". So where would be a good place to start? Electrical or fuel.

When my 9N does that it's the points adjustment too tight. I Guess the rubbing block wears. The last time I replaced them from NAPA I used the included lube. So far So good.
Kinda sounds like the the carb needle has allowed gas to leak out, and its still in the carb throat when you go to start it.( instead of leaking on the floor) So it floods when you hit the start button, then clears one cyl at a time.
Found this bit of teflon tape under the needle on a new to me 8n. Yep, the crank breather smelled for gas. Changed the oil, cleaned the carb. Now it runs nice, no leak ( used the same needle/ seat)

It does sound like it's too rich when starting. Open the throttle about 3/4 when you first try to start and see what it does. As posted above a weak ignition will cause starting problems as will a stuck needle allowing fuel to overflow the float bowl. Do you shut the fuel when you park it?, it's a good practice. As for Teflon tape I just say no to it as it can cause problems like mentioned above.
