Does Lycoming make any sense?

This is just at idle?
Are your manifold pressure and rpm readings in line with each other?
I am thinking about cam shaft wear.

I just spoke with Lycoming regarding my very high fuel flow. Recently
I've had a problem where I'm getting almost double my normal fuel flow
at idle even with the mixture at the edge of cut-off. I suspected a
servo but called Lycoming. They said I may have a nozzel with a
blockage and the other nozzles are streaming because of it.
Does this make any sense? Could a blockage cause an *INCREASE* in fuel
flow?
I have a JPI fuel transducor wheel that measures fuel flow that has
shown to be very accurate.

Anytime. However, it is a little bit intermitent. Sometimes it "clears"
itself.
I can't increase throttle w/o increasing mixture but I *MUST* keep the
two perfectly in line, if either gets in front of the other the engine
dies. It really feels like there is no fuel regulation.

Probably the blockage in a fuel nozzle moving around.
