A fellow Barner here in town was having starting problems with his '30 Roadster, it's got a Tilly, and I wondered if my Zenith would have been a seamless "loaner".... (I've got a flat firewall on my April '31 Cabriolet). Also, did the Tillys get reconfigured when the '31 firewalls were modified? Thanks, John

The Tillotson and Marvels just bolts on. Gas lines, throttle linkage and GAV all line up and connect like they should. Same size fitting on gas line.
