I have been there a few times. You can do this with any car(in the past) but if you want to engine brake down a large grade it better be fuel injected. Engine braking with a carburetor is gonna blow your exhaust up as soon as you turn the ignition on. Also engine braking will retain your power brakes whether they are vacuum or hydraulic.

Most new cars are so faggoty you can't even do any of this.

I've rolled into gas stations before after running out of gas. Pretty awesome feeling of relief. This was all moreso when I was younger and broke, only buying gas as needed.

OK. Bosch also made a mechanical gasoline injection system that used a pump similar to a diesel, based on similar systems used on aircraft to deal with problems with float bowls during high G manouevers. I don't think they have been in common use for 50 years. What you are talking about is the K-Jetronic system with the fuel distributor sitting atop an air box with the round metering flap. Easy enough to maintain if the fuel is kept clean but the distributor is considered factory rebuildable only. It's a messy nightmare like you described, requiring special jigs and gauges to set it up correctly. the pump is worth as much as the car. https://www.hemmings.com/parts/item/Air-Intake--Fuel-Delivery/Fuel-Injection/Porsche-911-Bosch-MFI-Mechanical-Injection-Pump/19835.html '

I've had to get more than a few Mercedes with K-Jetronic running properly without factory rebuilds. Monitoring fuel pressures on either side of a diaphragm because that REALLY matters. It's the main control after the fuel slits. By slits I mean actual slits. The air flow meter "plug on a stick" moves a piston up or down in a slitted cylinder allowing more or less available fuel.

And if you've had any fuel quality issues, like perhaps... Ethanol. Or any other contamination LOL get fucked!

I might be telling you what you already know but I had to fix them by utilizing thousands of slides of Microfiche. For fucks sake. All that shit belongs in a museum or a collector's garage. Not in the garage of the average Joe or a grandma with sentimental value.

Yup.

I haven't worked on a K-Jet for some years (other than routine stuff). I'm getting ready to put several ca 1980 VW water cooleds back into action and dread discovering that a fuel distributor is mung. I can rebuild the control pressure regulator but I never did serious work on the FD and hope I don't need to. Just in case, where did you find the data on rebuilding?

Within the Microfiche. The shop owner was an old school german car guy because that's what he had worked on in the past. The Microfiche reader was a backlit screen projector side by side with a cathode ray oscilloscope on one of those huge diagnostic center roll around things.

Y'know. The things everybody junked because they were obsolete and just taking up space. Good luck finding that kind of stuff.

Most people think you're talking about a small fish when you say Microfiche. And I'm not even that old, early 30's.
