so the carb was running lean for the first 500 miles and I had at least a dozen back fires through the carb (possibly more). After speaking with smeding and quick fuel I was instructed to richen the idle mixture 1/4 turn and haven't had a single carb back fire over the past 200 miles.
I Did a quick google search and from what I found it seems a blown power valve would make idling very difficult at all times (is this not the case?). But once I finally get the beast properly started it idles great and runs perfectly.
Thanks!
