[Willit Stop]

I could use a little input here....the dwell is correct but when I play with the timing slider I can get a smooth idle but it runs ragged at higher RPM's.When I advance the spark,it runs smoother at cruise but rough at Idle.I found that the weights on the advance plate were a LITTLE sticky so I cleaned and oiled everything.My question is,what is supposed to be used to lubricate the plate and weights?Oil or grease?From reading other posts,if I understand correctly,the porous bushing nearest the engine block receives oil from the cam,but is it enough to lube the weights as well? Thanks
