Hi guys, thanks for the replies so far.
Tidnab,unfortunately your systems require me to be looking up a particular carb and have its designation ie HDA-56.
But i do not have a carb. I need the list of venturi and bore sizes to choose one, if you get my point.
My choice of carb will be based purely on those dimensions, hence the need for a listing of those specs.
Earlwb, , yep, tried your system and i agree it works. However. sure takes a lot of searching, not that i'm lazy!!
Just wondered if there was a listing due exclusivley on size????
