Leaking fuel lift pump diaphram??

Are you getting an excessive amount of oil/gas in your engine pan from
the air baffle?

If so, the gas line may be leaking and it might be one of those
situational things. A friend of mine has the same FICHT I have and
had a really interesting problem in which the fuel line had a teeny
little split and it dumped fuel into the baffle which caused the
engine to do much the same as your describing.

The only other thing I can think of based on my limited experience
with FICHT engine repairs (~~ snicker ~~) is that the pump itself may
be hiccupping for one reason or another.

Sorry - can't do better than that.

Tom,

Thanks for your info. I called Bombardier tech support. They are
actually pretty good to deal with; no wait on hold.
You get directly connected to technical folks.

They suggested that either
the fuel pump diaphragm was leaking (#1 possible cause)

or that the TPS was screwey (much less likely).

The leaking diaphragm would however make it run fast after
the engine was sitting...just the opposite of what I see.

I will check the fuel lift pump vacuum lines. If they
are full of fuel I will have my culprit, if not I will probably
button up the motor and go fishing.

They are terrific folks aren't they?

Glad you have an idea of the problem. Good luck with it.
