Hi George, ease off the nut on the gas line to carb joint a couple of turns. If fueal weeps out, you know you have gas that far. That may clear an air lock and solve your problem.
Chances are, you have a stuck float. Old days it used to happen a lot, tappins side of float bowl gently a few times with wooden hammer handle may free it off.
Probable causes tho, either the float has been attacked by something in the fuel and deceased itself, swelling up or generally deforming and refusing to move, or as is increasingly common, a nasty reaction has occured between the gas, the float bowl and the bottom nut, causing your carb to jam up with a whole heap of nasty crystalline growth. Seen this a good few times in the last couple of years, must be something odd occassionally appearing in the gas.
To explore further, you will need to remove the gas line, the L shaped carb steady under the float bowl ( if fitted), and remove the large nut at the bottom of the float bowl ( 1 inch wrench needed for this. Float bowl will drop free, along with the spring holding the main jet up ( this will probably stay in place) and the issue should become clearer. Let us know what you find and then we will decide where to go next.
Are you in Eastern Ohio? Have a friend, Steve Benson , near Canton, who is one of the best Triumph mechanics around, and he is also pretty handy with Indians. If you get into difficulties, he is reasonably priced.
