[QUOTE="thedude, post: 456584, member: 23372"] So I may have solved the idle problem. The cam throttle roller circled in the picture was worn on one side down to the metal. Simply rotating that around made it idle much better. I also adjusted the low speed jet screw but didn't want to tinker too much with it. The electric choke/primer also was set high on manual setting so reset that to stock automatic setting. I think it was resulting in excess gas sitting in the carb (pictured below). Also seemed to idle better once I got the vacuum hose hooked up to the air cover and got it all buttoned up (I was running with carbs exposed before). Video of idle. https://youtu.be/113gGu1UGO0 Also included some pics of my helpers! Good day all in all.
