Poor idle when hot

[John Peak <redbn7@yahoo.com>]

List,
 
Perhaps some of you can help me diagnose a problem. My BN7 (HD6 carbs) runs 
great and idles smoothly until hot.  By hot I mean like after driving for half 
an hour in 90 degree temps (I live in south Florida).  It then becomes unable 
to sustain an idle.  It just idles rougher and slower until it dies.  I suspect 
an ignition problem although all components were replaced within the last 18 
months.  Any suggestions as to likely culprits?
 
Thanks,
John
