YUP! Chief, my dad and Guru of Model A stuff, rebuilt carbs down in the woods of Oklahoma, NO electricity, I worked a tire pump with a pointy pipe in the hose while Chief blew out the passages & jets. He cleaned the carbs with Lye soap & water in a cast iron pot hanging on a hook in the fireplace. He "built" Model A's to sell, so we could EAT. He was associated with Buddy Boggs, the county's un-authorized Model A Heaven, and Bill Ogan, the hometown Authorized Ford Dealer. I've got a "million" Model A stories, if I could remember them all!
