Yes but, generally speaking, all the same things apply. Toasty tan is the optimum color, very slight soot on the base ring, and the annealing midway on the ground strap. I bought Don Gould's tuning guide here and it really helped me learn a lot about how all this works. Spark plugs are a periscope into an engine and if you learn this stuff and the basics of how a carb works, you can really get your engine purring.
