i just got mine back on and to my suprise it came to life after the second pull, and it seemed to idle fine. that was on the bench. i will give it a try outside in the morning hopefully it will be o.k. thanks for the info you guys posted. air leak? what air leak, i had my setting off. being concerned about not wanting to go past "factory settings" is why i took it off in the first place. i will let you know late how it runs thanks for the info guys!!
