But then i read this on their website and I see the thumb warmer as standard...

ThxWhen they are cold they are lean. Once they are run for awhile under hood gets very hot and since air is much warmer then they run much better. If you rejet for the lean symptom when cold it will transition to sluggish rich running once it gets good and warm. Need a cold air intake pullig from out of hood so more consistent air temps to jet for.
