Interesting topic as I have a 2003 360. My problem is that when I come to a stop engine will just die. Starts back up no problem. Took my carb out and cleaned. Blew out passages. Reinstalled. Started it up and would do same thing your experiencing, idle fine, give gas and die. No smoke in my case. Carb position not friendly for trying to adjust set screw. At last resort decided to try something. Started engine, put choke on about half way so I could get engine revved up. Raced engine this way wide open a few times and they with engine revving slowly back off choke. I'm guessing there must have been something in a passage somewhere as engine started running normal without choke on. That problem is out of way but still have to find out what is causing engine to die when coming to a stop.
