Hmmmmm...........
IMO...A "skip", is a mild grind, really not a loud idle tone, but a little bit of eight cycle action going on.
A lope, is kinda a gallop really, kinda a "potato potato potato".
Then there is the "chop"....
Anyway, "slobber" is like........a louder note at idle, but also kinda like the exhaust, uh, "slurs" together? Kinda, uh, wet sounding....uh, gee, I don't know how to describe it........ Kinda like the timing is a bit more retarded maybe. Certianly SOMEONE knows what I mean, and can do a better job of explaining it.
Or, just put the cam in, and listen!
