    Well after a bit of craziness and newbie-mistakes I got everything adjusted to the specs Big T recommended (110 jet, needle clip down one notch, air 2.5 fuel 1). I got it all back together and sync'd with the vacuum tool.

    It's running pretty decently now, enough for me to at least get the victory lap around the neighborhood I've been looking forward to.

    So now I'm on to the plug chops, and I've got a couple questions on those:

    Am I supposed to use a new/clean spark plug for each test?

    When adjusting the pilot circuit, it sounds like I adjust the fuel screw based on plug color and then go back and adjust the air screw based on highest-rpm method. Is that right?

    Thanks for all the help
