Not to poke the bear, but I had a clone carb on my 327 on my Chevelle that I bought new from Pep Girls, and it ran flawlessly from day 1 until I sold the car 10 yrs later. I also only drove the car to cruise nights and an occasional run at Cecil County Dragway

The 350 in my truck has the used 1400 on it that I mentioned before in this thread, and so far it's been OK. I did notice, though, that someone spun the electric choke cap so far counter clockwise that the chokeplate was always open, and the wire tabs were in the 12:00 position! No clue why, so I've adjusted it back to normal.
