This has been popping up on my motor for the last 2 years and I cant figure it out. During a full throttle pass (street or strip) the throttle sticks open. Makes for a exiting slowdown at the end of the track. I have checked the carbs (dual eddy 800's) and they appear fine. Springs are correct, butterfly's close all the way, no clearance problems.....sticks open about 4k rpm and I have to flutter the pedal to bring it back down (sometimes it does not want to come down)This is a new 496 (under 300 mi).
Anyone ever had this happen to them?
