The round topped one is a TLDM, the DFT is the one people refer to at the "sqare top" carb but it still has round venturi's.
DFT:
The main difference between the DFT and TLDM is that the DFT has bigger venturi's and has a mechanical linkage to open the second V instead of a vacuum operated one. This means it doesn't "back off" when the vacuum gets low - ie. cruising speed.
It wasn't overly difficult to set up, but the proper manifolds for them are quite rare and the carb would no longer fit it after I replaced the auto choke with a manual one. Hence I had to modify a 1400 CVH manifold to fit it instead (the foot print of the DFT is the same as the 1400 DFTM, but the TLDM is different).
Modified manifold:
Basically I've ground out all the holes to be the size required for the 32/34 DFT carb.
Hope this helps.
