I think I'm going to pull the valve cover to actually measure the travel. I've been chasing a sporadic hesitation, and I've gone through everything else (ignition, gasket, power valve).
Just to give you an idea, all the other lifters line up with the top edge of the bore when at the cam heel (valves closed), and they rise up to what appears to be just about 1/4".
That one lifter "appears" to be just under 1/4" below the top edge of the bore at the heel of the cam, and then it rises up to maybe 1/8" above the top edge of the bore when the valve opens.
I guess what I should be asking is, how small does the movement of the valve have to be to start causing problems?
