spray some PB Blaster on the injectors, nuts, fuel fittings. Allow it to sit
and do its "work". Proceed slowly. Oil down the cylinders or fogging oil down the cylinders liberally. Crank the engine many times by hand. If you feel any kind of "catch" S-T-O-P.
My late mentor in this businees had a setup where he could take the oil pressure sending unit out and put a hose in and remotely pressurize the system with clean oil....pre-lubing as it were. He would do this on major rebuilds. His was electrical
but I am sure you could setup something with a small brass bilge pump
