I knew NOT to try a quick start up. This is the fourth 1950 Buick I've worked on over the years. Oil pan was removed and everything checked. Old oil actually looked pretty clean. Rotating parts were tight, not sloppy, and moved easily. Luck??? Oil pickup cleaned out. Timing gears and chain replaced. Rebuilt 1952 intake/exhaust with rebuilt 4br was installed. Rebuilt starter. Converted to 12 volt. Starter was used to crank engine to verify good oil flow and operation of all lifters before a live start was attempted. Rewired the entire car with a new YNZ wiring harness. I have about 170 miles on it thus far. Great ccompression and no oil burning noticed in exhaust. Installed a new gas tank, replaced entire gas line, new filter and electric fuel pump. Also rebuilt/replaced entire suspension and brake system. Recored radiator. She's on the road!!!!! I beleive she was parked for several of the items I fixed, the cracked exhaust manifold/radiator/starter and awful carb being major issues, not to mention a wiring harness patched with scotchtape in places!!!!! I'm replacing the entire hydraulic system for the window, seats and top with 12 volt components.
