Hello all, new here. Anyway Iíve just fitted a new out the box Holley 390 auto choke 0-8007. And was hoping I would have to play with it. Itís bolted to a Offenhauser intake manifold with 1Ē spacer with single hole on a small block Rover 3.5 V8. Basically, it runs very well, but itís idling at 2000 RPM. Iíve not tried anything yet, except removing throttle rod from car. Any ideas please.
