Over here you can pick up a set of carbs with manifold etc fairly cheap from a scrap yard ’cos all the bodies have rusted away from the mechanical bits! Although they may be getting scarce now! If you are having REAL problems then a carb conversion may well be worth thinking about, although it will work out more expensive than the $40 you are looking towards at present!

The poor/rich setting is completely identical and there is only one (1) device that is operated by the TA. So TA's are identical as well (but some have a straight in stead of a 90dgr connection of the tube) Extension is the same (see graph in earlier mail) -- Ciao from Holland AlfistaGJ (Gert-Jan) Now: Rosso Radicofani GT 2.0JTS (2005) Golden Montreal 1428700 (1973/4) And former owner of: 156SW / 2 155's / 75 / Giulietta / 2 33's / 3 Sud's / Alfetta GT / Montreal / 2000GTV / 1300GTJ / 2 Giulia Super's |
