Why does my car have a issue that I can not find a answer to?

I have an issue with my 1995 toyota corolla 1.6 lt. It has a problem When I set the timming 15 dg btdc it runs poorly. It bogs down when accelerating mostly happens when car is warmed up. Also spark plugs build a black carbon around them. But when I advance the timming it runs perfect but still has alittle bogging to it. Either way it runs poorly up hill will not exceed 25 mph. And does not do so great on gas. Here are some things I have changed.
