Sounds like the typical Carter YF carb. These were used on 195.6 L-head (flat head) engines as well as Jeeps, and many other appications. Jets and such will vary by application, of course. I pulled two from L-head 196 engines and both had different size main jets. There was only a year or two between the cars they came from, but apparently one was set up for high altitude operation (larger main jet). I didn't notice the jet size difference at first and ended up with a hole burned in a piston -- I ran them on a fabricated twin carb intake on a 196 OHV. _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
