I have an 71 USA import with servo brakes and a 1600 tp. Been trying to get it to run well, got rid of the 009 disy for a standard vac one which has improved things a lot , but the carb is a Brazillian one which I and a good mechanic cant seem to get setup well. Ive been told that there are some Sth African versions available that are of a better quality. Does anyone know anything about these , are they any good , or should i go for a Weber , or what else ? :?
