    Guys,

    Just did a tune of the carb now I have my vac gauge, the only thing is I had to do it without the aircleaner on as it's too large and impossible to get at the screws with it on. Will it make much of a difference? What hg reading should I see at idle on a standard AMC360 with MC2100?

    I believe the standard is in the 18-20 in. hg. range, but with any sort of aggressive cam expect in the mid-teen's. I pulled vacuum readings from the back of the carb to measure manifold. I got the steadiest readings there.

    What is your rpm at 18.5hg? 650-900 is good. I personally like around 750-800 on mine.

    RPM set at 690, might increase slightly to help on the trail. I would say I have the mixture screws at 2 1/4 turns out.
