    After tuning/timing it floats between 18 and 19.




    Is that good?

    Crower level 3 cam, 800cfm qjet. Stock everything else. 800rpm idle, timing at 10*btdc. Runs really smooth, like a burbly sewing machine.

    Nothing wrong with that. Mine reads at 16-17 and I believe I've read on here 16-up is what you are looking for.
