'73 2.0, a yellow storage unit find Options

[arne]

Arne,
McMark and jcd914 and I discovered during a tuning of Jims (jcd914) Dwight Mitchell motor that you cannot let the MPS sit on top of the motor. Ran like crap until we put it in its proper place. Not sure if it was grounding or EMI, but it cleaned up after we put it where it belongs.

Interesting, Rob. I did go ahead and mount the MPS properly, just because I didn't like the thought of it lying loose in there. So that shouldn't be a problem for me now.

In the garage right now, back to work replacing lines and hoses.

Injector seals... (IMG:style_emoticons/default/icon8.gif)

Wow. I think those are spent. Cheap fix tho.

Spent is probably a good description. Or perhaps, as Edd China would say, "Perished."

[arne]

Picked up new injector seals from a local shop who specializes in busses and Vanagons. All of 50¢ each. Have all the hoses under the hood done now, will probably crawl under the car to relocate pump and start pulling lines tomorrow afternoon. Hoping to finish and attempt to start it over the weekend.

Got the new stainless fuel lines installed in the tunnel today. Would have been easier with a second person, but not too bad as it was.

Also installed the new fuel pump, relocated to the rear firewall. Found that a PO had a different take on vapor lock prevention - he/she pulled the cap off of the right side heat flapper and ducted the outlet to the center of the car, using really tacky foil hose and lots of zip ties.

After adding today's work to the work over the past week (all the fuel rail hoses and new injector seals), all that's left in my fuel delivery refurbishment is to reinstall and connect the fuel tank. Once that is done, I will attempt to start it up. Maybe tomorrow, or Monday for certain.

Woohoo, it runs! First time for at least 6 years, more likely close to 8 years. Started pretty rough, was only hitting on two cylinders at first. Fiddled with plug wires, saw some extraneous sparks, got it running OK for now. New wires on my short list.

[arne]

Drove the Audi down to the FLAPS, got a decent set of wires, definite improvement, no more miss.

Of course, if not one thing it's another. During my fiddling with the wires, the auxiliary air regulator has now stuck wide open. Idles at ~2300, but if I pull the AAR hose and plug it, drops to ~950. Will need to see if I can clean that up, have some time to look at it tomorrow.

Going to start on the brakes soon, all 4 calipers need attention. Will Contact PMB to see if they have any of the DIY kits available, if not will need to bite the bullet anyway. May just do the fronts myself for now, don't want to get in too deep into my budget until farther down the line.

Congrats! Maybe it's just that the AAR wire came loose with the fiddling. That happened on mine.

Possible, as I could have dislodged it while fishing the new plug wires in. Will check that possibility first when I get to it tomorrow.

How old are your brake hoses? Brake hoses decay from the inside out, they usually swell inside and block fluid from returning. Could be the cause of your sticky brakes, and they're not very expensive.

Normally a good thought, and my original plan was to replace them as I do on all my new projects. But in this case, all four were replaced with braided stainless not that long before it was parked. Pretty sure those are ok.

[arne]

Despite the sticking brakes and intermittent AAR, it will now move under its own power. Just not very far or fast, and it stops by itself. (IMG:style_emoticons/default/idea.gif) First, second and reverse gears all work, and the clutch seems great.

Some gratuitous 914 brake p0rn.

Great find! The car looks like a real solid project. (IMG:style_emoticons/default/welcome.png)

As you may have guessed from my previous post, I've been going through the brakes this week. I disassembled and cleaned out the front calipers myself, and replaced the rears with a fresh pair from PMB. The master cylinder seems ok so far, and all the flex hoses are braided stainless installed by the PO. I figured I'd try to reuse the existing pads and rotors if I could get good pedal feel.

Today, I took the car for its first real test drive. And the brakes aren't going to cut it this way. The pedal is soft and has a lot of travel. I believe this is because whoever worked on the front calipers last didn't pay any attention to the piston orientation, which caused uneven wear on the pads. Now that I have the pistons oriented properly, the pads aren't contacting the rotor surface properly, and there is a lot of flex in the pads and rotors. No way to fix that without new pads and rotors, at least up front. Which also means new bearings and races. I'd hoped not to have to go this far, this early. But the brakes have to be right, no shortcuts.

Beyond the brakes, the car ran quite well. A bit smelly, I'm going to have to address the oil leaks soon after I get the brakes handled. The transmission shifts well, but seems a bit on the noisy side. The odometer doesn't work, I suspect the little plastic gear has broken. The suspension seemed very harsh and bouncy. I now think that all four dampers are seized, no real suspension travel is happening. That will also need to be addressed sooner than later.

But for now, real progress has been made.

Your car reminds me of Speedy.

I've got a ways to go before it is that nice. But I can say this, it will remain yellow.

Nice progress. I did a thread on fixing the ODO issue years ago, on the old NARP forum. It's typically a gear that starts slipping on a splined shaft after about 80k miles or so (same for the '70's era BMWs). I gouged new splines on the shaft pressed the gear back on and the ODO worked again.
