new lifter ?

I dunno, for 40 years-soak, pump up lifters; lately don't. What is up? Spring pressure will move the plunger back to normal.
Just fired up a 340 that hadn't been even turned over since 1987, primed it, started it, and had a tic. New lifters, from NAPA; 3 would not hand pump up. Got a new set, hand pumped up, installed, and no problems on that old purple cam.
