Recently rebuilt my carb. Sonic cleaned, new jets/rubbers. Got an extended fuel mixture screw. Good move. Bike starts way easier now with full choke. But I noticed when I kick and it doesn't fire. The motor lets out a "sssshhhhhhh" if you push kick starter slowly it hisses every time after a full kick down. Valves? Also, once and for all, what is the stock settings for this carb? Mainly the fuel screw.
