that's electronic ignition my dude.... It's probably not your issue. Here's how to check for spark quickly, be careful. On the dizzy, remove the boot that comes from the coil. Find a bit metal tipped screwdriver with a wooden/plastic handle. Wedge the screwdriver up the boot, place it on the block so the metal part is about half an inch from anything conductive. Jump the starter solenoid or have someone else turn the key. If you see electricity sparking across the screwdriver arm, you have spark.
But I don't think spark is your problem if you don't have problems running. Since it's cold where you are, do you have an automatic choke? Maybe rig up a manual choke. If you can see gas in the fuel filter, two pumps, choke on 3/4, and hold the key on start. A tachometer helps to see if you need more or less choke while warming up. As aforementioned with your flooding issue, if you get too much gas in the cylinders you need to hold down the throttle all the way to get extra air, to compensate. Use your head and realize that this is the opposite effect of the choke, act accordingly
