OK, so the new ring is in, put a velociy stack on the original carb, gave up on the new carb as Im sure its just bad, and cut a new base gasket for the jug as it looked as though the original was saturating with fuel and most likely leaking. Also put a G38 exhaust gasket on it. It idles happy down to 1300, and the top end with the zinger 18/10 is still around 6750 as long as throttle transition is slow (no stabbing the gas or it dies). Im at the point where I think it might just have to live relegated to more scale war bird duties. I'm on the fence about trying one of Speedy's carbs, kind of like the idea, kind of just want to be done with it.
