10.2 Tuning Procedure<br />
Here are the steps to get your engine tuned to the factory specification. Note that the<br />
three steps really just refer you back to the proper section. What is important here is to<br />
not go beyond the factory setting. Don’t “tune by ear” (yet) or “dial in” anything. The<br />
factory spec may not be perfect, but it is neutral.<br />
10.2.1 Basic <strong>Engine</strong> Timing<br />
Set your crankshaft to top dead center. Check that your camshaft wheels are lined up<br />
with the markers cast into the camshaft boxes or the pointers in front of the camshaft<br />
wheels. See the ignition section for diagrams <strong>and</strong> details.<br />
10.2.2 Basic Ignition Timing<br />

See the ignition section for diagrams <strong>and</strong> details.<br />
