That sure is blue, if it heat blue I wouldn't run it. Some of the strength is gone making it weak.

I'd also like to know what caused it to let loose...

Go back and read my post #19, the answer is there.

I just got it all back together. As I'm typing it's idling for 1st in and everything sounds good. I uped my oil to 32:1 and screwed out both low and high carb jets out 1/2 turn. Make it run a tad rich also its only in the 30's outside right now. I have to richen up my 200t whenever it gets below 40.

So I just checked how far out my jets were they were both a full 2 out so I set the low at 1-1/2 and the high the same. It had good response where it was at but my plug was soaking wet. But that could be from all the oil I used when assembling it.
