A few of the pics are different but everything else is the same such as what each jet does and how to change it.

look further in this section for jetting 101, it's a great write up.

duane 3, the correct way to read a plug is to run wot and immediately shut down. If it's still black, then and only then would I say it's running rich. You can also have a wideband O2 sensor put in the exhaust and monitor A/F ratio. The fact of the matter, running a bit rich is safe as is running a bit retarded. A lean condition can kill your motor as can having the timing advanced too far. Just saying.
