put the cold enrich to 100 that will solve your starting problems. You just need to tune idle for it not to run rich. Keep taking out fuel until it starts to stumble or pop a lot (lean misfire) and then add like 10% fuel and you idle will be set. Don't mess with any other fuel values thoug because you'll need a wideband to do those
