Rocker cover

No disrespect taken....

The cap was changed about 50 miles before I adjusted the valves.

I had started the engine with the cover off, engine warm, and, it started fine, and, had no flat spot (but, still with the misfire). As soon as I set the valves, and, restarted it started a bit harder, and, has a massive flat spot.

My valve adjusting method puts the lifter right on the backside of the base circle 180 deg opposite the lobe, so, well away from the lobe ramps. It helps eliminate errors caused by other methods, especially on hotter cams......

Haven't pulled any plug wires yet. Too awkward to do on the /6 while it's running.
