The Ford Barn - View Single Post

When I acquired my 1930 Sport Coupe it had a Tillotson and ran very nicely. While striving for authenticity I traded the Tilly for a Zenith that had been rebuilt by a man with a very fine reputation as a carb rebuilder. In fact he has written a book on rebuilding Zenith carbs. After replacing the Tilly with the Zenith the car did not run nearly as smoothly or with the same power level. With all kinds of adjustments to the Zenith I never did get to run as well as it did with the Tilly.

I bought a second Tilly, put it on the car and it ran beautifully again. My conclusion from my own experience and reading many Fordbarn and Ahooga threads on this subject is that for some reason some cars run better with a Tilly and others run better with a Zenith.

Yours apparently likes the Zenith. That new Tilly in the original box is worth some money. One recently sold on -bay for over $150.00!
