valve lash or bad/dragging starters
Of course you're right about that. I had been through my starter before, but went through it again and cleaned the grooves between the commutator segments, and put brushes in it although they didn't look that bad. Also had been running the precision cam at about 007-008 lash. Tightened to 005. Before, it'd only start on electric when cold, had to pull start assist when hot. I was thinking heat soaked starter field magnets in the argo engine compartment. After tightening lash and commutator/brushes it's been cranking when hot. I was surprised.
