It does idle a bit low when cold and then picks up. I want it to start really crisp. Valves rechecked and are just right. New fuel filters.

Anything else to check but the pump timing? I will make sure the rack dampner is not too far in.
Can you be more detailed on how the idle is after first starting? This will indicate a bad glow plug because one or two cylinder is not firing because the temperature in the cylinder is not high enought. After 5 to 8 seconds, then the fault cylinder will be working and the idle is higher. Black plug tip show bad, I have replaced plugs about every year now, in the past it was 3 to 4 years.

p.s. since the tank was full of JHB9&0-H, stick to the fuel system as the cause and related issues this will cause. In other words, remain focused....
