Hi All

Have seen this on an unrestored car…does anybody have anymore details…? I assume the 022 refers to the 1.7L but what about the other number?

Any insight would be appreciated…thanks

breakthrough?

1. example from your exceptional cars on website.
74 1.8. build early Jan 74. emission sticker is EC-A California + 49 States.




engine tune sticker. note hoses are shown on these stickers - and indicate whether hose is on or off for setting initial idle. sticker indicates hoses off as per 1.8 tune. only 1 hose is shown.





2. wonki car.
74 1.8 build end of jan 74. emission sticker is EC-B california + 49 States.




engine tune sticker. sticker indicates hoses off as per 1.8 tune instructions. 2 hoses are shown. (the sticker is heat/age damaged but you can still see the two hoses).




i never looked at these things closely before for different VWs. eg examples of tune up stickers for late model buses. these have idle set with hoses on. tune up sticker shows that. dumb cartoons but deadly accurate.








conclusion.

EC-A (cali + 49 states) has 1 vac hose connected from dist to TB.
which one i am not sure yet, its hard to tell from photos of engine bay of blue 74 on your website.

EC-B (cali + 49 states) has two vacuum hoses connected from dist to TB.
wonki + StarBear cars.
advance dist (left) to advance TB (rear of car). retard dist (right) to retard TB (front of car)

now whats an EC-B that is only 49 states?
you have one of those stickers on your website.

EDIT - re marathon blue car on your website mr. b
i have looked hard at the images of the engine bay on your website.
interesting stencilled engine number too - 607 maybe, but first letter is degraded and illegible.
what i can see with a reasonable degree of certainty is that it runs a vacuum hose from the distributor advance side to the TB port facing rear of car (advance at cruise).
BUT thats not what the tune up sticker is saying. its saying one hose only. further disconnect retard hose on distributor at idle tune up setting so thats the only hose. (if there was a second fully connected hose VW practice with the stickers would be to show second hose and to show it connected) which means it should have a hose connected only to the retard side of TB. further its saying there is no advance line connected. (which given other accounts of distributor hoses would mean there was a hose on distributor but it was left lying open and tucked under the dist). so something is inconsistent between sticker and engine as photographed. i doubt anyone would change an emission sticker or a engine tune up sticker. (its possible - however they both look aged/original but in good condition). more likely would be throttle body/vac connection changed/modified along the way.
need other examples to nail this one.
but it is an EC-A stickered car. and tune sticker indicates only vacuum retard activated, not vacuum advance. those two clues are saying that much about an EC-A car.
