Not Ranked
I have swapped out two vacuum secondary carbs for mechanical secondary carbs on two different engines in two different cobras. Both engines seemed to come to life. Throttle response was noticeably better, fuel economy stayed the same and seat-of-the-pant's acceleration felt much better.
Worth the $$$ to me. And a well prepped mechanical carb will set you back about $750.
