First check that the points are in good condition, and set to the proper gap, next set the timing. If you do not have a timing light, disconnect and plug the vac. line to the distributor, and using a vac. gauge set to highest vac reading and then back it off a bit until it does not ping. then adjust to specified idle speed then adjust the mixture screws one at a time by turning them in until the engine starts to stumble then back it out just enough to get it to smooth out. this should get you good results if done properly and the engine and carb. are in good condition. I am sure others will correct me where I am wrong.
