Brad, without being there and hearing it, it sounds like ign to me.
Go through those points again and set em dead nuts .017"
BTW package went out today.
I actually set them a little tight at .014". I may have found a problem though. The post that the point rocks on is loose in it's mount on the backing plate. It does have constant pressure on it from the spring, but might cause an issue at RPM.
I played with the tuning on both this saw and the S25DA from the raffle. They both act very odd in reguards to tuning. Without the air filter cover on, it's seems difficult to get it rich enough to not go screaming lean at WOT. Put the lid on, and it stays rich, most of the time. Ocassionally, it'll still want to go lean, then rich again. The CVA has been pressure tested too. Are these things wierd like that, and just tune them where they run good in the cut?
I won't know until I get it back in the wood if I helped the ignition or not.
