The backpressure on the exhaust will have an effect on the idle speed, I've found out. (Had mine set on the muffs, was too low at the lake. Just a tweak, no big deal.)

You've got the terminals identified correctly, just need to know which setting on the switch. Check this box to be notified of replies to this topic. Note: BBcode and smileys are still usable.
