Jim, the reason my car has less than 80k original miles (still has the old shocks from 1975 installed!) is because the original Zenith carbs gave the previous owner of 35 years nothing but misery. He said he loved the car but got tired of throwing money at the carbs.

He attempted to rebuild them three times. I suspect he didn't realize they were probably warped so no matter how well they were rebuilt, they would never perform correctly. My Weber carbs take all of the drama out of start-up and running the car. They weren't the easiest things to install because the kit from RedLine wasn't all that great but I don't regret it now that the job is complete.
