Okay a year ago I had a garage that works on foreigh cars (I have used them for years) install a new carb replace all my fuel filters.  and now the car after I dive it less then 1/2 hour or so will stalls out... I have a full tank of gas so that is not the issue... I have less the 52,000 miles and drive it less then 3,000 miles a year... I have new gas I always use unleaded 93 oct.  I hate to keep sending it to the garage as its costly but if I need to I will.  any ideas what now could be wrong?

I  would start with checking to see if you have gasoline getting into the carbs.  You need fuel and you need spark.  So those are the first and second places to check.  Have you run the car much since putting on the new carb?  If not then it may just be that you need to adjust it. It is likely that a new carb was not adjusted prior to shipping.   So if your garage did not adjust it properly then you will need to. 
Just because you have a new fuel filter on the engine does not mean that it is letting fuel past to the carbs.  You can check this yourself by removing the fuel line on the carb side of the filter and crank over the engine.  Be ready to contain any fuel that does come out!!!  I have not worked on Strombergs (I assume that is what you have) so I will not try to tell you where to look for fuel there.  Maybe somebody else can help you from that point.

I agree with Charlie 100%, you need to determine if this is a fuel or electrical issue first. However, noting that your mechanic replaced a carburettor and fuel filters, it would seem that an issue existed before that work was done. I have no experience with using ethanol/gasoline in my Triumph (it was put into storage before e10 came out) but I've had considerable trouble with it in old outboards. Essentially, it loosens all the old sludge and varnish and clogs the screens, filters, carbs and lines. This condition seems to be exacerbated by fuel "stabilizers". The problem is solved by scrupulously cleaning everything. While I don't want to suggest that this is your problem, the symptoms are similar. I wonder if anyone has had issues with ethanol/gasoline in classic Triumphs? Tom Mulligan
