    Manual choke; when cold in the morning, you pulled the choke knob out to choke (additional butterfly, cable controlled to block free flow air to go into the carburetor) to make the air/fuel mixture richer. As the engine warmed you pushed in the knob. Same sort of thing still on a lot of lawn equipment today.

    Thus my statement that today's "turbo muffler" idea is based on the wrong technology for today's exhaust system flow characteristics.

    (another Spyder power level control was the single throat side draft carburetor - the bore was sized so that it came very restrictive as the air velocity through the bore approached the speed of sound - airflow would not go any higher. It was a dancing act between the intake airflow and exhaust backpressure. One way we used to coax more power out of a Spyder was to insulate the entire exhaust header/pipe system - hotter gas = more delivery to the exhaust turbine)

    EDIT: Do I remember correctly - the Spyder had to be idled for a minute before a hot shutdown - to cool the turbo bearing to prevent oil coking ?

    ............. No electric starter solenoid on my '53 MG - Spring-loaded manual pull knob on the dash - right next to the choke knob.

    I never heard of a Manual Transmission until 2009 when I got my first CTS-V. Up until that point, it was always called a Standard. I figured that it was because that generation V was not offered in Automatic, so calling it Standard, which implies that there is at least one other optional transmission, would be a poor choice in terminology.

    Still, it is my natural first thought to refer to a "Manual" transmission as a Standard.

    Cars without hidden fuel caps are uncivilized. Probably what lesser primates would drive, if they could drive.


    Funny thing about leaking license plates though. That was the first thing I ever had to do to my Lincoln. Immediately after buying it and filling the tank, my friend who was following behind mentioned to me that petrol was pouring slowly from the fuel cap, which was of course behind the license plate (until 73 anyhow)

    Where can I find it on my Northstar car?

    That's not a trunk. It's called a boot. It's on the opposite end than the bonnet, which is up at the front of the car and usually houses the auto's motor.

    I am no expert on how to use them though. My Cadillac has five doors, no boot. That'd be creepy and peculiar.

    My Jag E-Type and Lamborghini 350, not to mention my Jag XK 150, all had manual chokes. The fifties and sixties cars required that you depress the gas pedal once or twice before starting cold. Fuel injected cars do the choking automatically.

    In that case, we should probably also mention the windscreen (which one looks out to drive) and the repeater (which tells others of your intention to turn)

    That is correct. They weren't as free flowing as glasspacks but noticeably quieter. And they had a 2 1/2" diameter!

    50s and 60s cars? Hell my 80s V8 cars require that (granted they are rarely driven). In fact, the smaller FI V6s (2.8 and 3.1 IIRC) requires you to "prime" the system by pushing the gas pedal down twice before starting.

    My cars are ritualistically primed before turning the key. Face of habit. Floridian climate does probably occasionally mandate that, due to the mix of temperature and humidity level we receive.

    The obese I drive less often probably require it, but I think the Pontiac would start nearly any time with or without priming. The Lincoln on the other hand, when I first got it, ALWAYS required priming unless it had already been ran in the last ten hours.

    Those are not repeaters. A Repeater is a small compact crossbow that can fire two bolts in rapid succession before requiring reload. Those lamps on the sides of the car to indicate the direction you intend to turn are called "Blinkers". Contrary to popular belief, the device used to activate them is not a rod, but a stick. It's proper title is a Blinkerstick.

    The-Dullahan does not retire at night. Even so, I sleep very, very rarely, so my counterpane remains for the most part entirely untouched.

    Dave's on key, but all of my little lead knights went away with my childhood, so I've not had them for a good two decades.
