I don't know about them modern murdercycles, but here's what I do with my 1955 Hummer, which has a similar carburator to your Scat. Similar, as in only internal jet size differences. BTW, if you've gotten it really flooded, take out the spark plug and dry it off. Maybe kick a couple of times with the plug out to clear out excess gas. Also, disconnect the fuel line at the carb, and make sure you have a good flow of gas through both (but not at the same time) the normal and reserve flippers. If you don't have a lot of gas mix in the tank, you may need to use the reserve flipper.
What I do: Turn on gas. Close the choke fully - push lever towards front of bike. Open throttle about 3/4. Kick. Mine usually starts after 3 or 4 kicks. When the engine starts, quickly move the choke lever about 1/2 way towards the rear.
Often, I am not quick enough, and the engine dies after a few seconds - it's slightly flooded. So I open the choke all the way, kick once or twice, and when it starts, move the choke to the 1/2 way position until it warms up.
Carb and float adjustment below. If you can't see it in the picture, the float is 1-13/32 +/- 1/64
Hope this helps - Dave
