new distributer pro's con's

have a reman electronic distributer on a small block, checked shaftplay after 2k miles by hand, can touch pickup with relucter with little pressure, book says 1 pound, pickup plate seems to move pretty easily,flexing spring like.Question is is it worth trying to make this setup work better or just buy a 2 wire hei distributer set it and forget it , problem with set up now it breaks up evan in nuetral giving gas ,misses, plugs look ok clean ,wires are good, thinking relucter is changing gap and possibly touching at times, rotor has carbon trail at top of pointer not at tip, swapping motor out soon just want to get ignition good to avoid issues with new motor, motor now is 273 with cam and 4barrel, new motor 318 magnum cammed with 4 barrel. thanks everyone for opinions
