[Mgs] Carbs still being nasty

Original MGA carbs are H4. It is also possible for them to be replaced by 
MGB carbs - HS4 or HIF4. (HS = H type, seperate float chamber, HIF = H type, 
internal float chamber, the number 4 is a measure of the throat diameter - 1 
inch plus 4 eighths of an inch - 1 1/2"). Pictures of many SU carbs are 
available on Joe Curto's website: http://joecurto.com/carburetor-library

For almost anything knowable about the MGA (and most of it also applies to 
the MGB) see Barney Gaylord's MGA Guru Tech Pages.

For info about the MGA's H4 carbs see:

For tuning info: http://www.mgaguru.com/mgtech/carbs/cb130.htm I like the 
little tool kit shown there. I also have an SK Synchrometer (measures air 
flow). After using the pointers to synch the carb I've used the synchrometer 
to double check and always found it spot-on.
