^^^ Excellent! he did try the light & it was showing a miss but not sure what wire he had it on & agreed I would do all 8 EDIT If there is an open at the plug (not likely/I cant see how) or its plug wire (very possible) there would be no flash (no ground path) & if the plug is fouled to the point where there was no spark cuz the current dead shorted in the carbon to ground thru the plug base it would flash but the cyl would not fire. We need closure here!
