Hi Bob.
Let me expand on that.
I don't think you are getting enough fuel at the carbs. Which could be  
due to a wrong/ faulty pump (me), crushed line (Rich) or blocked  
filter/gauze screen (Ira) - same result, not enough fuel.
To check, disconnect your fuel line at the carbs, turn on the ignition  
& start pumping fuel into an appropriate container for a timed  
interval  e.g. 1minute.
If you have a e.g. Sprite or 100/4 type  SU pump (usually rated at 7  
or 8 imperial gallons per hour), you should have around half a litre  
of fuel in your container in one minute.
If you have a late type BJ8 SU pump (usually rated at 12 - 15 imperial  
gallons/ hr, depending on model) you should have  around 1 litre of  
fuel - under or over, depending on 12 or 15 gph - in your container in  
1 minute.
If you have a double ended SU pump (usually rated at 30 imp gallons/ 
hr) you should have over 2 litres of fuel in your container in one  
minute.
In our tests, at full throttle, my Healey can consume over a litre of  
fuel per minute, and can run quite happily on one end of the double  
ended SU on the road (I.e. 15 imp gals/hr)
Your mileage may vary.....
Test your fuel delivery volume first. It's cheap & easy. And if the  
filters are clean, and the line isn't crushed, but you arent getting  
closer to a litre a minute, then maybe try upgrading your pump.
