I started my MK2 tonight and discovered that fuel was gushing out of the
body of the auxiliary starting carburetter. After some brief
investigation
before dark I was able to determine that with the ignition on the fuel
pump
continues to pump fuel and it pours out of the aux carb at the rate
pumped.I
have had no problems till now and believe the fuel pump should not
continue
to pump with ignition on. has anyone had this problem or similar and have
any ideas on how o fix? To compound the problem my Jag mechanic is over
40
miles away and risk an underbonnet fire to get there. Thanks to all who
offer any advise.

Sounds like one or both of your float chamber needle valves are not closing
when the float chambers are full. Possible causes include punctured floats,
worn needles, worn seats and sticky pivots.

Your front float is not shutting off the fuel supply. Look for movement
of the float on it’s spindle. I suffered this.

Andy,
The pump is always ready to pump when the ignition is on. If the system
will accept fuel, the pump delivers. With a leak at the starting carb (or
anywhere else), the fuel pump simply does its job. The issue is the
starting carb, not the fuel pump.
If the pump DOESN’T pump, then the problem is the pump.
There’s a chance you can tighten the bolt that secures the starting carb to
the main carb. It’s difficult to access with the carb on the car, and
probably you won’t have a completely successful go at it. You could also
over tighten it an damage the carb body. It’s risky, but perhaps worth a
try. You can crawl under the car and look up at the intake system from
below and see what is going on.
Best thing is to pull that carb and tend to things on the bench. There is a
banjo bolt with two fiber washers that holds the starting carb in place.
This is a classic place for a leak.
Where the heck is Mandurah, anyway?
Good luck,

Thanks Tom at least I know which end of the car to work on.

Prawns are plenty.

Where does it go, will it just flood??
Who does your work on the car? I’m using roadbend at the moment, but
they’re bloody expensive.
Starting to get cold down in Mandurah is it?? Toodyay mornings are a bit
nippy!!!

The fuel seems to flow up what I guess is an overlow next to the aux carb
neetle, or is it the channel which air is meant to be sucked down
through?
Either way it is flowing out the channel which orms part of the aux carb.
It
ends up on the ground and the engine appeared to run fine, but when I did
further investigation last night it seemed to run rough, I think there is
some water in the fuel filter. I think I might put an extra modern fuel
filter in the line before the glas one.
I have had Roadbend service the vehicle and agree with your comments.
Starting to get little nippy first thing in the morning but days are
great.
