Thanks! Sorry that I was too lazy to look it up myself! It's interesting that the 195.6 has the same tube; you'd think that the trough intake would do that well enough without the tube. (And comically, the tube runs directly under the carb port, like within 1/2" or so, and really interferes with flow!) I'm certain Nash did this cut-n-try over the years and would not have wasted their time on a system that did not do something they wanted. _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
