Maybe we should change the title of this thread to "old Porsches."
Speaking of which, I now have my 1973 911 running again. My brother was here a week and a half ago, and helped me get the engine cranking over by hand, and then put the engine/tranny back in the car. Last week I fired it up, and found that the old bad gas had pretty much gunked up the whole fuel system. The ethanol-contaminated fuel just doesn't last like the pure dead dinosaur juice. It absorbs water, breaks down, and leaves crud everywhere if you let it sit for very long.
So I drained the tank, blew out the lines, had to squirt carb cleaners into and tap on the fuel pump a bunch of times to get it freed up and put it back in the car. Then I had to take off the CIS fuel distributor and squirt it liberally and blow compressed air through it to free up the metering plunger, and the same with the injectors.
Then it was running on 4 or 5 cylinders, which turned out to be too high resistance in a couple of the spark plug wires, but it took me hours to trace that down. Yes, I ordered a new set of spark plug wires and will put them in tomorrow. After all that messing around, it is finally running smoothly.
Next project is to clean and rebuild the brakes if necessary. After that, I will install the oil-fed Carrera chain tensioners. Then I can start putting back on the bumpers and the glass and last, the interior. Lots of work, but it's a fun driver with a 3.0 SC engine and about 230 ponies in a 2300-lb car.
