Ramon,

I do not doubt your good will and admire your effort to help others. However, to correct and make more rigorous the information you posted would be too hard a task. That is why I posted the Wedge Epistles for you. So that you could compare and improve your work.

There is nothing more frustrating for someone alone in their garage than trying to fix anything with insufficent information. We have all been there.

By way of an example, you dismiss, almost in its entirety, an explanation of the functioning and tuning of the very heart of the system, the Bosch L-Jetronic Air Flow Meter from which the whole setup takes its name, the "flapper". What you do offer is incorrect..or at least misleading as, in your point 4, where you simply talk about "dumb garages" and tell the owne, to set the idle air screw arbitrarily at 2.5 turns from the bottom becuase that is "ok". Why would you assume that? Adjustment screws are installed where it is envisaged that adjustment will necessary. If a single position was to suffuce, there wouldn't be an adjustment screw.

You also make no mention of the spring tension adjustment, the contact point for the fuel pump and how, in fact, to set the device at all. (It can only be set with a Co2 tester.)

As this is the most important component in the system, it is a MUST for people to understand it thoroughly. It is analgous trying to tune an old carb'ed car without touching jets, needles, idle and air adjustment. You mention Manuals (which do not exist for this AFM) and discourage them touching it when to ignore the Flapper AFM is to ignore most of the system.

Other areas have been similarly dealt with.

May I suggest again you start off with the Epistles. There is also a lot of other stuff up on the web and in my own archives that can take you even further. When you wish, I can send you much more and help you with it at your convenience.
