I made a major breakthorough over the 4th wekend!

My fuel pump always ran all the time with the ignition on. I knew this was not
right, but at least it ran, right?

Well, finally ther was athreadthat talked about this. Clay Perrine posted a
good description of the whole L-jet system, including pictures of the inside of
the airflow sensor.

Because I am stupid, but jst for fun, I opened my airflow sensor. The fuel pump
contact looked like it had been twisted.



The red arrow points to the contact. I straightened it out a little and tested it.
Sure enough, the fuel pump shut off, but would come on when the airflow
flapper was moved. But, ther was another problem.

The green arrow points to what I call the cam thingie. It rotates with the
flapper. It would hit the end of the fuel pump contact and cause the fuel
pump to shut off! SO, I decided to straighten the whole contact and bend
the silver arm a little instead.

Now the contact set looks like this:



Now here is a picture of the airflow sensor witht heflapper rotated part way.
it does not hit the fuel pump contact:



This also may explain the missing I had on the way home. At certain RPM's the
engine would miss badly. I think it was when the flapper was at a certain poit
that the miss would occur. Fuel starvation!?!

With everything hooked up, there is not enough vacuum to open the flapper. I
can only keep the engine running with my finger holding the flapper partway
open.

Now, back to the #2 cylinder problem, sigh.
