check plug gaps / tappets then when the engine warm try , dis connecting the timing vacuum advance , turn the idle up to about 1500 rpm. The adjust distributor timing to the fastest running point then back it off a bit. Then do the same with the mixture . start with the mixture screw running lean (more out than in). re-connect the vacuum qadvance then take it for a spin. if it pnking just kock the timing back a nadge more . it may help
