Even more tweaking

Yesterday I messed with the timing and the idle mixture to try to smooth out the engine. After trying one way after lunch and it running worse on the way back to work,  I decided to go even farther clockwise on the distributor when I was almost to work. I also put the idle mixture screw farther in. The result is a smoother running engine, nice power, and higher revving (got it over 5000 RPM this morning). Plus no bucking when not on the gas. It still likes to back fire out the carb before it is warmed up. Before adjusting the idle speed screw this morning on the way to work, it was idling around 400 RPM, now I have it around 900 RPM. The next thing to see with these settings is what will the MPG be.

A few things that I know need to be fixed are an oil leak near the oil filter (but not the oil filter gasket), a coolant leak, probably from the intake manifold to water pump hose and a leaky transmission, hopefully from the selector shaft seal.
