Bill,
One other thing, when I ran up the engines the twinsync seemed to be working because when I turned the aux switch on and off the engines would go slightly out of sync and then back into perfect sync when I flipped the aux switch. At about 3/4 throttle I killed one engine to see if the other engine would retard to idle, it did not retard, it just kept on screaming. Any ideas?

Thanks again,

Tom
