OK, I have finally gotten my second project car running.... The first time since I've owned the car (purchased 2 1/2 years ago)... (IMG:style_emoticons/default/driving.gif)
Anyway, I've done the following to the '74 2.0l engine: New: Spark plugs and wires Distributor cap Points and condensor Vacuum and fuel hoses Intake runner boots Other: Tested and rebuilt fuel injectors and new seals Timed the engine Adjusted the valves I hooked all vacuum hoses, per AA's diagram. When I started it, it ran at 3000 rpm. I disconnected the AAR and plugged the hoses. I've gotten it down to 1500 rpm, but it was 'hunting'. I soaked the AAR valve overnight and washed out the PCV with carb cleaner. I hooked both back up, but it ran at 3000 rpm again. So my questions are: 1. How do I test the AAR valve to verify it's working? 1a. If I remove it permanently, do I just plug the line to the CSV and wrap the electrical wire (the plastic plug is missing)? 2. I've ordered the TB gasket, do I need to remove the runners before I remove the TB/base? 3. After I remove the TB/base and check for pin holes, anything else to check? 4. Any other suggestions? 4a. BTW, I tried spraying carb cleaner around the TB, injectors, runners, but didn't hear any difference in the engine sound. Also, I researched this subject and found Jack's (championgt1) posting, but there was no resolution, at least in that thread... -- Rob |

Update:
Well, I didn't work on the car this weekend, I'm still waiting for the TB gasket to arrive... Anyway, I noticed in one of the ads that someone was selling the phenolic spacers for intake manifolds and they mentioned that some of the spacers were missing the gasket, so I got to thinking. When I 'cleaned' these spacers, I removed a paper gasket material, but didn't replace, so can this be part of my vacuum leak issues? If so, can I just make a paper gasket and attach to the spacer? -- Rob |

I need one & can't find a supplier on the vendor list for my 1974 2.0 liter F.I. re-do. I am also checking out all my AAR valves & will probally need one. They are expensive & wondering who has the best rebuilt prices & quality?? I was thinking Otto's or maybe AA. FYI: I just purchased a $75.00 dollar "Vacuum Line Kit" from AA and dissappointed they are not supplied in factory color anymore. They are all black/grey standard (correct) hose sizes without instructions in the package. I need to call George and tell him about this issue. Now I have to do a search on the subject. I am in the process of dyeing the hoses with the the proper CW colors (redish, brown, green & standard colors). (IMG:style_emoticons/default/mad.gif) Tom |
