That makes sense, though wouldn't they become more reliable over time? Would you really lose up to 10k MTBF going from 1bbl to 4bbl? Also, now that I think about it there's a post about engine families. Will MTBF in the future be improved over time by sticking with the same family of platform / engine?

If you stick with a certain feature through the years, for example OHV, you will get a quality boost for that. I'm sure it will work the same way for carbs.

Re: Carbs and Reliability
There are several things owners of vintage cars tend to not realize.
Lead in gas to protect valve seats for example. Most guys put hardened valve seats in to combat that when rebuilding older motors just to find out they ruined the heads. Some motors CANT have hard valve seats and/or don't need them due to high Nickle content in some heads. Buick nailheads are a great example of this.
Then there is ZDP in motor oils. Modern oils have a fraction of what they used to. ZDP is critical in our flat tappet valve trains to keep the lifters from flattening the cams. Most older car owners have no idea that without the zdp they could tap valves, wear out the cam, or worse! That's why I buy ZDDP for every oil change and full synthetic oils. You will be supprised how well our baby's love synthetic oils! Runs cooler, more power, more efficient who can complain bout that?
