We talked about the plug heat range, carb. jetting, timing light accuracy and jetting, the AFR where fat and the symtoms he was having.

Fuel was Esso 91. I can tell you the weather was similar both times. In fact I can tell you that density altitude was 1800+ feet both times. Weather aside the Correction Factor was almost identical both times. Raw power was up same amount as Raw power before. J.Rob
