I just bought an engine with a DX 5 in it. I'm not familiar with all the cams yet. Any info will help. I also discovered it has a moon power carb and an ARC billit rod. I think the deck has been trued up. Also its odd but the plug is clean dang near but the top end is pretty sooty as well as wet. Wish I knew what they had going onI still use the 96-3 old master grind. The old 96-3 grind is still hard to beat.
