Thanks everyone. Pulled the regulator out. Cleaned it real good. I didn't find anything that looked dirty, but who knows. Checked the valves. They look good also. Pulled the throttle barrel out. The rubber o ring had a part of it that was missing. Got two on order. One other thing I noticed was that when my throttle barrel goes to almost closed it gets tight to turn. I checked it with a flat straight edge. It doesn't appear warped. Don't know what I'll do about it. I may have to buy a new barrel. I also changed all fuel lines after checking the tank. They all looked fine and pressure tested fine. But I figure it couldn't hurt to change em. Just waiting for Central to send the o rings now. I'll post if any of this worked. Thanks for the help. Chris
