This is old information, but still absolutely viable. Because of the differences with modern fuels, you may have to make some experiments to get float levels and injection right. Remember these specs are only guidelines. The 1968-2400cc engine capacity is actually pushing the limits of the Zenith. You might want to consider going to dual carburetor if considering an engine that big.

There are many other variations to be considered, like camshaft timing, altitude, overall engine condition. Look at these settings as being guidelines, a starting point. Remember, at idle, all engines tend to run rich. Keep your spark plugs clean so you can read and maintain your engine performance.
