I used to have one on the mach before. It was a good simple carb. Just a bolt on and go, not much tunability for performance though. It wasn't terrible was a very nice daily driver carb. Also very easy to change the jets on it.
Just make sure not to overtighten those torx bolts that hold the top cover on, they will destroy the gasket and strip out very easy. Ask me how I know.
the 4010 is a very good carb for the street, much like the 4100 autolite. there are subtlties in tuning that carb, like the 4100, that most people have yet to understand. unfortunately most carb tuners never took the time to understand the carb, and thus the carb never became popular.
