" From: Tom Jennings <tomj@xxxxxxx> " " " Turns out I have RC12LYC Champion plugs in there. The "L" " means extended electrode; I got them from a local parts store " by looking up "83 Jeep". They should be RC12YC, not "L". Either " they didn't notice the L, or they substituted, and I wasn't " paying attention. the L shouldn't matter. 12 is the heat range, and if it's a 12 it should be a 12. " So I've mailordered RC9YC's, and will play with timing with " these colder plugs when those arrive. this should be the significant change. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
