    Hi Don,
    I can say I have spark on all 4. Since the new coils went in I get a fat blue/white spark on my open air tester set at 7/16". After running and pulling the plugs out they all look identical. They all have the same amount of soot and color to them, none wetter or dryer then the others. Attaching a timing light to all the leads and watching the flashes shows an even flash all around.
    The timer base does move freely in both directions and the key and keyway are good. I did torque the flywheel nut to 105 per the manual.
    The prop I was running before is a 3 blade no name 13 X 21 stainless. Yesterday I was running a 3 blade 13.25 X 22, custom cupped and drilled with ventilation holes at the base of the blades. It’s an OMC Raker I got from Dan Anderson at Tomahawk.
    I’m almost convinced most of my head aches were with the carbs. Rebuilding them today made a world of difference in how it’s running. I will have to wait till I can get it back on the water for the real test.

    Do you think the 18 degrees is OK with the timing? And what about plug choice?
