i just got off of the phone with ys and the spring under the regulator screw was resversed, the taper of the spring was backwards, now upon fueling it i'm not getting any fuel past the regulator system. i screwed the regulator all the way down and tried fueling it and defueling it. than i tried it with the regulator screw flush with the regulator body and now it's working the way it should. once it's gets above 32 degress i'll go out and try to start it. hopping for the best
