I KNOW this Matt! I just removed it TEMPORARILY to see what would happen at maximum flow through there. BUT, since you remind me now, and it IS mid-day. I'll go ahead and drop a 180 F poppet back in. I just retarded the timing back to the spec 7.5 degrees BTC, and it seems to idle a little smoother. I know retarded timing usually = MORE heat, but I want to be sure I'm on spec, and will then work from that basis. Let's see what happens on a 75 F day, with everything on FSM 1968 spec.
