[Shop-talk] new project need mechanical advice

[Randall]

After adding fresh oil and you pull the plugs, squirt a healthy dose of your favorite penetrating oil (eg PB Blaster or Kroil) into
each plug hole.  Let sit for a few hours, then spin the engine with the plugs out.

After changing fuel and removing injectors, run the pump long enough to flush out the lines with fresh fuel.  Check for water in
what comes out.

I don't know how the engine is arranged, but if it doesn't fire quickly, I'd look for some way to verify that both cams are turning.
