Spark advance tuning made simple and quick?

[Bob Valentine]

Break out the Electric Hot Metal Glue Gun (aka mig welder), tack weld the
mechanical advance so it doesn't have a chance of moving, also make sure
the vacuum advance isn't letting anything move either.   

Unless you're planning on going back to a carb, there should be no reason
to  keep mech + vac advance around.
