Well, I am convinced that the interrupt switch mechanism is perfect.
I now understand perfectly how it works.

I am now assuming that what occurs when I have
the difficult shifting is:

The engine does not throttle down correctly; it is staying
at ~2000rpm.

So even though the interrupt switch drops three cylinders,
the engine is still running way too fast for the load to be
off the shifting mechanism.


So what causes Ficht rpms to stay high?

Leaking fuel lift pump diaphram??

Faulty TPS??



Why would it not be consistent?

And how to diagnose it when it is intermittent?




Help!
