John,I`m just about sea level and I`ll try the stock needles.Grump,I checked the diaphrams and they look good.Al,I did`nt take the carbs off,just removed the bowls.Pete, I`ll try the stock pilots if the stock needles don`t work.Thing is this problem is only on left side!Am going to put new plugs in just to eliminate that possibility.It looks as though the left side is not firing above an idle,as the plug is black. Just thought it was too much of a coincidence for a plug to go bad after working on the carbs.Is there a chance that the left float might be stuck?Appreciate the help guys!
