I have recently picked up a '77 fj40. I live in Colorado and do not have to worry about emissions testing in my county. The engine looks to be set up like one of the California models with a ton of emission equip. I am thinking about removing all the excessive vacuum baggage. Will I need to change out the carb in order to feed the vacuum advance to the distributor? I will post the project as I get into it, but I want to have a good game plan first. I want to build it as a weekend driver, not a serious crawler, but something to have fun with.
