Of course not to argue your point and I'm grateful for it but just to make the picture clear I did just back it down the two degrees and change brand of spark plugs. The Heat range and GAP are the same as I've used for some time. And also those plugs have been in since I've had the new cam since the end of last summer.
I know it gets hard to read everything I jabber on about but again it's on the left side just passed the collector and everything done by the instructions and looking like it's working correctly.
Here's another thing to throw in the twist- at 2800 RPMs it had a bit of a spider jumping on the throttle at first. To me it seems like the accelerator pump. As well as the AF gauge going up and then plummeting down and then leveling back out..
