Also check your accelerator pump for zero lash
I've heard several ways of checking zero lash on the accelerator pump. I was told to WOT, then with a 1/4 in wrench push down on the accelerator pump arm, then measure the clearance between the arm and the linkage. That should be at .015 with a feeler gauge. Is this the right method, or is there a better one?
