For a hot start I've found MOST cars with Webers like it if you hold a SMALL crack open of the throttle while cranking, and they fire right up.
Cold start: 2 pumps(maybe 3 depending) and turn it over until it fires, then keep feeding SHORT stabs of gas for the first ten seconds. Then hold it steady until it starts to smooth out. You don't want to rev it over 1500-2000 rpm in your startup process. After 30 seconds or so it should stay running on its own.
