    I've got a vacuum advance lockout kit. Just wondering how he set it up to adjust it where he needs it. Maybe when I pull the distributor, it will become more clear.
    Hope to start on that project next weekend, depending on if I get my other three projects completed: house water filter system install, replace the K5 alternator again and figure out why they keep burning up, figure out the code in the '04 Chevy truck and what it takes to fix it (probably the O2 sensor), but trying to figure out which one.

    Yes, it will be. Start with the vacuum advance lockout kit installed. Then you'll need to run the engine, synchronize the idle timing by turning the distributor, tighten the hold-down bolt, then check rotor-phasing to see how much you need to shorten/lengthen the vacuum advance link arm.
    May God's grace bless you in the Lord Jesus Christ.

    OK thanks. Got my three projects complete. So unless the new cats for the wife's truck come in this week, I'll be tearing into it this weekend and will report back how it goes.
