Every "N" has a bit of it's own personality, and once you catch on to it's little quirks with choke operation and throttle position for starting, you're well on the way to more reliable starts. If mine will sit for more than an hour or two, I always shut the fuel off while it's running, and let it run a minute ot two to cool down and burn up SOME of the fuel left in the carburetor. This prevents the flooding scenario that can occur if the carburetor input needle and seat aren't quite up to the task of controlling gas flow, and keeping the carburetor air horn (and beyond) from filling with gasoline. My carburetor works well, and it would be unlikely that it would overflow and flood, but why take the chance? When I'm ready to use it again, I turn the gas back on, and get the engine cranking over at about 1/4TH throttle, and give the choke a quick tug-and-release. Experience with your machine will tell you if that is enough choke, or at what temperature another quick "tug" or two may be needed, or if a different throttle setting works better! I think "flooding", especially in cold weather, when the gas is not as volatile, and someone cranks the engine with the choke out too long is one of the biggest reasons people get frustrated with these old machines. It does not take long to get quite a quantity of gas in the air horn and air intake tube by holding the choke on too long! This leads to wet sparkplugs, making starting difficult, if not impossible without replacing the sparkplugs, or at least removing them and burning them clean with a propane torch. If you have a good battery, starting system, and ignition system, these old girls will start VERY reliably, once you've tuned in to their "vibes" a bit!
