Pinto Misfire & temperatures

[deezee]

Sadly there is seemingly no solid settings for carbs to get the engine to run perfectly. From experience your going to need to check for air leaks (A common causes of exhaust popping), balance the carbs, do a compression test and fit a wideband lambda to the exhaust. Unless you can see what's going on in the engine, your going to struggle to tune the car. Popping can be caused by lean conditions in your engine. Which you have no way of knowing without a wideband.
