What the heck, I'll jump back in though I think this thread is through. And since it's got nothing to do with a C-Dory, I hope that I'll leave some of you bemused, not pissed.
First, lets set a baseline. My first (drivable) car was a '29 Ford Model A. The brakes were drum, front and rear, but rod actuated. That meant the more people in there, the less brakes. The carburetor was updraft with a manual choke rod, no air cleaner. And third, ignition points, which aren't bad, except that the spark plug leads were thin strips of brass. If there was a heavy dew, no start.
So let me list the 3 best improvements in recent automotive history. First, hydraulic disk brakes. For those of you who haven't gone down a hill, loaded, with drum brakes, you've missed a heck of a thrill. Of course, I mean the truck loaded, not the driver. That's another subject.
Second, electronic ignition. Again, some of you may have missed cleaning and setting the points at random intervals in some out of the way dump, but I haven't. And the plugs last forever. Though if the computer takes a dive, it's instant death.
And last, fuel injection. No cleaning the jets, setting the float, adjusting the air screw. No more jiggling the choke or changing the jets for altitude. It's been replaced by the $1000 fuel pump (for GM products,) and random warning lights. But when it works it's awesome.
So nothings perfect and for every plus, there's a few minuses. But the only drum brakes I own are the rear ones on my '63 Chevvy and the travel trailer. Every motor has electronic ignition, including the Honda generator. I still have a few carbs on a couple of oldish bikes. And the lawn mower.
