Old excavator 3 yr. overhaul

I FINALLY got the engine back together and installed in the old broke down excavator for the cost of a .020 crank from a bankrupt warehouse in florida (with rust dots) another rod and a box of gaskets (except valve cover)
i finally cranked it over yesterday … man, i just could not get that fuel moving., and i got some smoke from the blower intake only …but the fuel. jeez, you otta try getting that 3rd bolt off the fuel pump… it’s fine but keerimany, it’s like it isn’t even turning … ?? At 1am I realized i’d not installed the damn blower drive shaft … what a maroon. what next?
