I too own a 1971 Triumph . Mine is a Tiger 650. A bit of advice on your new carburetors. A number of people, including me, had trouble both starting and idling after installing the new Amals. Turns out a bit of manufacturing swarf can get caught in the pilot jet hole. They make a pilot jet drill bit for cleaning it out. You might want to do that before you install your carburetors.
