FC quit running

[Jay Darst]

Appreciate the suggestions on the Facet pump...

Dan was able to get started again...though can only run in high gear
at 50mph. When a hill climb is required, he must not push the
throttle too hard as he will have symptoms of low fuel delivery(such
as very little or no boost).

When the speed reduces to a point where 3rd gear(of 4 gears)is being
used, the fuel and boost return to normal full power. However, as
soon as 4th gear is engaged, almost immediately, boost level reduces
to 1-2psi and thus away goes the horse power. as we slow down and
then back to 3rd gear, an immediate 10pounds of boost and all the
horses are back.

Going down a hill with throttle wide open, reached about 63mph with
10pounds of boost, then, while continuing the downhill run, the
boost reduced to 1-2pounds and the Bird slowed to 50mph. Where it
will run all day, with 1-3 pounds of boost.

After changing the Racor, it ran bad, as before the change. So he
stopped and changed the secondary fuel filter, reffered to as
the "CAT" filter, I suppose to differentiate from the Racor filter.
Noticed that the fuel level in the Cat filter was down maybe 2
inches in the filter.

Dan replaced the Cat filter with new, primed with the Facet pump and
the little hand primer pump, and the bird started and ran, BUT, NO
CHANGE. Still not making power as it should.

Generator has been running the whole time, no stumbles, no problems.

The Racor gage is at 1 or 2 inches of vacuum, so normal.
The filters are fresh.
The fuel is fresh
The wire to the "Fuel Shut Off Solenoid" is good. By the way, that
wire, if broken, causes the Cat to NOT run at all. Been there done
that.

A fuel delivery issue for sure.

Plans are to remove the bottom bowl from the Racor and clean the
swirl tube and check ball.

What else?

Thanks for all your help!
