77 t140

Hello all! im also new to this sight but not to triumphs.
I have a 77 t140 that i have been working on for about a year got it from a guy close to green bay and slowley its getting there. i do have a problem. she starts on the first kick, runs great, idles great but when i shut down and wait more than 5 or 10 minutes she needs to be tickled again? the float is set to specs, and i have two new amal 930s runs perfect threw all gears lots of power just must tickle more than i should. help! should the floats be set a differant way?

Worth checking float levels. Has your bike got standard air filters? Standard silencers? If no air filters and louder silencers, this will call for a richer mixture - have you tried just screwing in the pilot air screw another half a turn or so? Its also wrth bearing in mind that each cylinder doesn't necessarily need identical mixture settings - I've had bikes that I've ended up with very different pilot air screw settings in order to get running right, eg: one turn out on one pot, 2 1/2 turns out on the other. If it runs well once going it must only be a minor idle mixture issue.

Mr. Tucker, I was always told to run a Bonnie with the two petrol taps open. Because the one carb is connected to the other by pipe. If one tap is open the petrol fills the nearest carb first therefore one cylinder will run slightly weaker especially at speed...G.
