John Elle has a better memory than he thinks! I've had problems in the past with the choke tube rusting/breaking/leaking INSIDE the exhaust manifold. I drilled the old tube out and carefully inserted a piece of steel brake line in. It might leak a slight amount, when cold, but everything expands as the engine warms if the tube is a snug (but not so tight it won't go in) fit. The same steel can be used all the way up to the carb, but copper will work as good. If you're getting carbon inside the choke housing the tube has a leak inside the manifold. Should be nothing but air in there! _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
