Sure! Just wrap that sucker up with a case of beer and mail it on over here! :-D
Seriously though, the first thing to do is talk to the shop that did the repair/service. If they're reputable (and want to stay that way) they'll find the problem and fix it.
Was this a Triumph dealer or an independent?
Did they give you an itemized list of repairs/service done?
Did you at least get a kiss before they handed you the bill?
This is actually a difficult problem to figure out with the limited information you've given -- moreso because I can't smell the gas tank or carburetors from here!
If the bike was sitting in a hot garage with fuel in the tank then you've either got severe varnish or the dreaded varnish and rust combo in the fuel system. If the fuel tap was left on then you've got lots of crud and varnish in the carburetors.
If the shop folks knew what they were doing, they cleaned the tank and carbs thoroughly. If it wasn't a Triumph shop they may have missed the tiny 'duckbill' filter that's hidden in the 'T' connection where the fuel line enters the carbs.
If that's clogged up then you'll have fuel starvation problems, but you should be able to go a tenth of mile or so before the bike dies -- if the carb bowls are filling properly before you start the bike.
When you start the bike, do you start it with the choke on? Will it run with the choke and die when the choke is turned off?
If that's the symptom then the pilot jets are plugged with varnish and need to be removed and cleaned. That's an easy problem to miss if somebody just does a 'dip and blow' cleaning on the carbs.
We'll need some more detail to pinpoint and solve the problem(s) if the shop doesn't come through.
Sorry I can't be more help at this time.
