Even that much out of wack can make starting more difficult. It is all a balancing act. Everything, the planets, my wifes mood, have to be in the correct alignment/adjustment to make an engine run. Once the valves are re-shimmed, a fresh properly gapped plug is in stalled, it should start a bunch easier. On my WR, even with the larger starter jet(#72) I still need two twist of the throttle to prime. Then it starts nearly immediately. The larger starter jet enables the engine to keep running. With the stocker (#68), It would start, stall, start, stall, then start and run.
