which one is easier to install in my car?
which one is easier to fix?
Answer
A carb was the only option for a gas engine till the 1950's. In the 1950's there were some systems that were mechanical (like diesels). They used a mechanically driven pump to inject the fuel into the intake. There was a brief experiment with an electronic system that was used on WW2 aircraft but I read they only made a few of them and they were all replaced with carbs. 1975 electronic fuel injection became an option on Cadillacs. It was standard on some models starting in 76. Early 1980's most cars were EFI and the trucks by the late 90's. Last carbs on cars and trucks were 1990.
A carb is a totally mechanical device. The engine rotating creates a vacuum. This air is sucked through a tube. This tube has a small hole in the side with gas behind it. As the air passes the hole it sucks some gas with it so you then have an air fuel mix getting sucked into the engine to be burned. For a steady state this is a very simple very reliable system. Things like farm tractors used a carb that was this simple till quite recently. Small engines like lawnmowers still use one this simple. Cars dont run at a steady state, you are constantly varying the speed and the load so they had to get complicated with things like idle circuits and power valves. By the 70's and 80's they got quite complicated trying to meet emissions and make them fuel efficient.
Fuel injection has some sort of a high pressure pump and then some method to vary and distribute the fuel to the individual cylinders. Mechanical systems could have had an individual pump for each cylinder or a single pump and some sort of distributor valve to send it to the correct cylinders. Electronic fuel injection has a high pressure pump and then basically an electrically controlled valve for each injector to meter the fuel.
As for which is easier most people go with carbs because they are afraid of electricity and computers. You can get complete bolt on EFI kits now days and there is a lot of info out on the net on how to modify junkyard systems to older engines if you want to go that route.

What model of car was commonly used as taxi cabs in the 1950's?

I'm writing a book that takes place in the early 1950's and I need to know what kind of car would be very common for cabs. Also, any info on tires would be very helpful. Did car manufacturers have a lot of different types of tires back then or were they less varied?
Answer
Well, congratulations on your wishes to be an author. However, your research skills are, shall I say, truncated? First, verb tense. When you asked to as to the kind of car, then the past tense applies. Allow me: "...I need to know what kind of car would have been common for cabs (of that era)." is my impression of the correct tense and I added a phrase at the end so the reader is reminded of the intent of the question. So, research. Ms. Internet knows all, has photos of all, can find references for all. I just plugged into Google Search the question and, presto! as if by magic, information as to cabs from that decade were located, photos included. Same for tires. Same for anything. So, plug your desired words or phrases, etc. via Google or your preferred search engine. Best of luck on the research and with the book. Bye.
