I'd go with this too.  A standard SU pump should deliver at least one 
Imperial pint per minute, but in practice closer to two, in a steady series 
of pulses with minimal bubbles.  How did you check the timing?  Did you do 
an advance test?  Stuck centrifugal advance could cause this as well. 
Disconnect the vacuum pipe and plug the (presumably) carb port, then rev the 
engine with a timing light on the marks and check it does advance.  To make 
things easier with the pulley notch against the TDC pointer (which I presume 
are underneath) make a paint mark on top of the pulley where you can see it 
from above so you can rev and watch at the same time, you are really only 
interested in does it advance significantly when revved, not the exact 
readings at this stage.
