@StarBear & @wonkipop want to hear from members who own 1974 1.8s.
to assist with a topic in originality section of the website. Cars need to be reasonably original with L jet fuel injection system intact. If you have the time and can help us with some information it would be great. information. 1. Vin Date - month and year (no need to post vin numbers if you don't want to). thats the date on the driver door sticker. 2. Karmann plate #. or if you have already done the maths, the day and week of the year the car began production. 3. Image of engine bay emission sticker (lhs above the air cleaner - white with red letters). sticker should say whether it is an EC-A or an EC-B engine and whether it is california + EPA or only EPA. 4. image of engine tune up sticker. this is the small white sticker that is on LHS engine tin just below fan shroud. most of them are gone by now, but some engines still have them. 5. image of the throttle body. image of the distributor. we are looking at the vacuum hose set up between the distributor and the throttle body. ----- (IMG:style_emoticons/default/beerchug.gif) |

i cracked the Executive Order open a little bit more.
i found a specfication description for a retard and advance function distributor included in the Executive Order A-7-6 covering the 74 Kombi Van fitted with the dual carb version of the 1.8. the dist is described as C-V-VR. = centrifugal + vacuum + vacuum retard. compare it to the A-7-5 covering the EC-a engine 914 1.8. the dist is described as C-VR = centrigugal + vacuum retard. if they were talking about our cars with the EC-B sticker it would say C-V-VR. our cars have the vacuum advance and vacuum retard. (vacuum = vacuum advance function). also our tune up sticker matches that dual functioning distributor hooked up. in this E O they are talking about your cars (L-Jet 914). the EC-A cars with only the distributor retard hooked up as supported by your original tune up sticker. so the EC-A cars are approved in california from Jan 29th 1974 on for 3 months and a further 30 days and from March 25th on for 3 months and a further 30 days. which gets them to the end of production for 74 MY. the EC-B cars are still missing in this documentation from CARB. we know they conform to California and EPA. (or at least their sticker claims that). i think it would be reasonable to conclude that EC-A cars kick in for sale in california after end of jan 74. (they might be making them in production a little earlier but they hit the showrooms for legit sale after that date). which begs the question, what were porsche selling in their cali showrooms as a base model before jan 74 for MY 74. they must have had something to offer? |
