    I need to adjust my carb to get a better idle and a little better low end response.I will reset the timing too.
    It is a small 4ble 500CFM on a 215/200hp. stock with a high rise.
    and will change out the accelerator pump too, has a bad stumble off the line with the AC on.
    The air and fuel screws and turned out 3 or 4 turns out now.
    Do I put a vacume gauge on the manifold and adjust the screws out to I get the highest reading a vacume?
    How should a proceed.
    Any ideas
    Thanks
