Everything 1quickS says is true. I’ve rebuilt my Zeniths once and after a carb fire and tow had no option but to pay to have one rebuilt again. If I had to do it over again I would have rather had a nice set of PMO or Weber carbs.

I live in Phoenix and the issue with fuel percolating out of the tops of the carbs at anything over 80-90 degrees Fahrenheit is a real problem. Running 95 octane with low ethanol in the Summer helps a bit.

Zeniths are not bad carbs but They always seemed like a compromise designed to meet emissions first with drivability and performance secondary considerations. In my opinion the other options may be better but Zeniths can be made to work well. Just watch out for fires in the warmer months. Usually happens after driving the car, parking, and starting up again after fuel has percolated out of the tops of the carbs.
