The quick and dirty method of checking for vaccum leak is spraying starting fluid through a straw around manifold to see if engine change's. Set a fire extinguisher where it's handy before you begin. Regarding timeing,are you aware that TDC come's up TWICE,(once to compress and fire then again to exhust) on each combustion cycle? You might try pulling distrubitor then restabbing 180 degrees.My current thinking is a possible vacuum leak in the intake manifold.
