Hi, I'm restarting a Pantera that has been sitting for 20 years (#1255) and am going through all the usual issues. The carb is a Holley 750 vacuum secondary and as I recall was never dialed in correctly. I'll be rebuilding the carb, but have tinkered with it a bit while I'm waiting for the rebuild kit to show up and hopefully this time with no missing parts. I see on Youtube that a lot of people are installing wide band 02 sensors and how they are using them to accurately tune their carbs. Has anyone installed one, how has it worked for you and what recommendations do you have.
