Easy, this is in the last 40 years and I've had a nice variety of cars. Fiat 124 I think it was a 1970. I'll admit I drove it a bit, and it was sporty, but 74,000 miles and it was rusted junk.
Sorry Mark but you can't stick things down just about any carburetor any more to start your engine and if you do it may break it. You are correct many have fuel injection, so it doesn't work.
