I haven't had much luck with the Werks P3. I have a feeling that the carb is a problem. The o-rings are getting trashed while trying to set the needles. I've pulled the needles out twice, & cleaned rubber shavings off of them both times. I wasn't sure where to get o-rings, so I figured maybe I would just try out a new carb. I'll be pulling the mill apart to make sure there's nothing in the case tonight. It just doesn't want to run at a higher RPM. Idles fine, but as soon as you raise the RPM, it dies. The needles have been tweaked in & out trying to find a solution, but no go.. I even had Ed & Christian try there luck at it, just to make sure I wasn't goin insane...
