Well, I guess when I installed the can, I totally misunderstood the limiter (this piece-

so it was advancing the timing right off the bat. Once I threw that out, I just had to adjust the can so it wasn't advancing at idle. Easy to do when you have a better understanding of the function....
Fully screwed in, it was adding 22 degrees at idle, so I just unscrewed til it was perfect! Easy as that. I don't even think I need to add a limiter like in the thread you linked.
