Hi John, and welcome to Spyder World. You’re doing it right. You don’t touch the throttle for startup. The Spyder motor, in your case it is the Rotax 998, is fuel injected and throttle by wire. But yes…sometimes that motor could act like it is flooded. And yes, a fuel injected motor can get flooded. It just means that there was too much fuel, not enough air, and the plugs got wet. So, what to do about it.
If it just keeps cranking and refuses to fire, you do a thing called a Wide Open Throttle start. All fuel injected motors have that mode in the computer…even your passenger vehicle in your garage. BEFORE you begin cranking, hold the throttle wide open. That action tells the computer to cut off the fuel to allow the cylinders to clear out. THEN start cranking for about 10 seconds-ish. Then you release the throttle and try a normal start. Just don’t overheat the starter. Patience. Repeat if necessary.
And sometimes, we can trigger a flooded situation ourselves, by letting go of the start button too quickly and causing an aborted start. Don’t be in a hurry to release the button. The computer stops cranking when RPM increases, and there is a Sprag clutch in the gear train between the starter and crankshaft. You can’t break it. Just release the button when you have a start.
If it starts but runs rough and misses for a few seconds, or is giving you that flooded but trying to start behavior, then yes, you could simply have a dribbling injector. That overloads the cylinders on startup. It doesn’t take much. Do a fuel system cleanup with those Sea Foam or Lucas Oil fuel system cleaners. And if you don’t know much about the previous maintenance history, a thorough inspection of the intake system and air filter is necessary. Once you take off the mirrors and plastic panels the first time, it won’t be so scary.
An inherently common problem with the 998 is crappy plug wires and cracked vacuum hoses. I can’t and don’t want to go on for another 10 paragraphs about that, but it would be easy to do. A lot has already been written about those topics. Do a forum search for those topics. You can use Google to search this forum, too. Sometimes it’s easier. Also, read through this thread for items pertaining to your machine.

I’ve been running and dealing with my machine for 10 years. I love it but they have a personality and it’s a learning curve. PM me your number if you ever want to talk off line. Glad to help, as would all of us.
