Hello Have a great offer for Quadrajet carburettor. Since the builder has already been assembled for many years and sometimes heard overhauled I want a replacement. Only problem E-Choke does not want it point. Is it possible to convert the E-Choke to the older variant or not? It starts very well. Problem with the old one does not crack at full load at partial load. At idle also not. Start problems also not. Choke works and opens. The vacuum box for 2nd level can man Where does man get the new one?
