I don't think its the spark plugs. Either the Champion or NGK should work fine. It might be electrical or timing. There are a number of things to look at...coils, power pack, stator, timer base and the actual timing. Oh yeah, don't forget the rectifier. Since you are at sea level, try experimenting with high speed jets. It sounds like you may be too rich if it isn't electrical. Those are a few starters before you go looking into the power head itself.
