    Bill, are you giving tours of your work? :) I'll be in Durango this Saturday and Sunday visiting my father in law on our way through the area. What part of town are you in?

    i need to tune this thing for elevation.
    i took it for a drive today and in 45 minutes was at about 11,300 feet and it started dying and backfiring on me.
    would elevation cause this?
    or am i all mixed up again?

    Could be. You're at 6500 or 7K feet at home?
    That's a lot of altitude. Or not a lot of air, depending on how you look at it.:)

    it was running like dookie this morning.
    i went through 97 pages with the search on this website this morning.
    if i try to use the choke it immediately dies.
    i couldnt take my foot off the gas for a second or it would die.
    so i jammed a stick on it and fooled around with the idle speed and fuel/air screws until it at least it would keep running.
    i had to up the RPM quite a bit.
    this is what it sounds like.
    any input /advice?

    You might want to recheck the points gap and ignition timing. When was the last time you adjusted the valves? I had a similar problem a while back and the value adjustment resolved most of it.

    The motor itself sounds good!;)

    The RPM fluctuation, is that what you're referring to? Sounds like maybe a vacuum leak.

    If it was a vacuum leak, closing the choke would help..

    Yeah, go ahead and check for vacuum leaks. What I was saying tho, is if it has a vacuum leak(s) it should run better with the choke partially closed.

    spray wd40/starter fluid/etc around the carb, vacuum lines, intake, etc while it's running.....if you get a noticeable change in idle you've found the leak :beer:
