Spark plugs = Champion J4C or J6C, gap set to .030 . The J6C might give you better performance due to the engine's age.
Points = Have flywheel key aligned with fiber rubbing portion of the points. Set points so that a .020 feeler gauge passes thru but a .022 will not.
Gearlube = HiVis 80/90w, available at Wal*Mart, K-Mart, your local dealership.
Mixture = 50/1 = 1pt of 50/1 TCW-III oil to 6 gal gas. A octane rating of 87 will be fine.
