JoeW, when I was in my mid twenties and newly married, I needed a new carb on my '54 Ford. Being a lowly corporal in the AF I didn't have that kind of money and decided to rebuild it. Hadn't ever done that before, but this was affordable on my pay. A kit was $2 then. I got the carb torn down okay and was ready to put it in a container of cleaner (a corrosive cleaner we used on jet engines). I slapped the open body down across the palm of my hand. When I righted the it, I had a BB in the palm of my hand. Panic mode set in when I looked at all the diversified chambers and drillings in the body of that carb and hadn't a clue where the BB came from. This was the weekend and I needed that car to get to the base Monday. Luckily the AF had instilled in me the necessity to read the manuals and read them again. And again if necessary. I poured over those instructions in the kit and decided with much qualm that the BB had to be the check valve in the accelator pump. There was an open hole there now and the BB fit. So that's where I put the BB when I reassembled that carb and reinstalled it on the engine. And lo an' behold, after some priming, that engine cranked up and ran like a dream. I felt like the luckiest guy alive. And greatly relieved, too. I wouldn't be AWOL Monday morning, but I had been sweating bullets.
