Well, that clearly gives you something suspicious to 
investigate.  Earlier you said "When it is at idle it will run fairly 
smooth. When I take it out for a drive it seems that it is starved 
for power. The rpm gets to aprox 3500 and the power runs out."  If 
you were really getting nothing at all out of the rear carb, I think 
your symptoms would be a lot worse than you describe.  Fairly smooth 
on two cylinders?  I don't think so.  Further investigation is 
definitely indicated, though.  Do you have an "SU toolkit" or 
uni-syn?  You should be able to get some information on whether or 
not the two carbs are responding equally.
