Eric,
The float you are showing has been retrofitted to the bowl. This looks like
a float from a smaller and newer carb like a HS2 the float bowls are the
same size but the fuel pressure is usually different. Also is the needle
valve plastic? If so I had a terrible problem with the overflow and found
that when I changed the needle to a brass non spring loaded tip it was like
magic NO more gas weeping.
My 2 cents
Dirk

Brian,
Charging the battery with a battery charger without disconnecting the
negative terminal (earthed terminal) is okay for a car with a generator but
if you have an alternator it can damage the diodes in the alternator's
rectifier (the thing that converts the AC output to DC). There shouldn't be
any risk of damage to the radio.
There is no danger, just risk of damage to the diodes from inadvertent
voltage spikes. On modern cars with computers controlling various functions
the potential damage extends to these too.
You could fit an isolator switch in the earth lead close to the battery and
use that to disconnect it from the rest of the car while charging.
When charging, a lead-acid battery releases hydrogen which is of course
highly explosive. Hydrogen released from a battery being charged under the
bonnet can freely escape whether the car is being driven or not. A battery
in the boot however is a different story. If car is being driven and the
sealed battery box cover is in place then the gas will accumulate inside the
cover until it fills it (from the top down) and is pushed out through the
drain hole in the floor. There isn't much free space in the battery box -
it's mostly full of battery.
A fully-sealed battery still produces hydrogen but is fitted with vent
valves to prevent pressure build-up. Modern battery design has reduced
gassing somewhat but t still happens, particularly if you don't have a
regulated battery charger and you over do it a bit. But having said that, a
good controlled over-charge occasionally is good for the battery's
longevity.
If the cover is not fitted or is not sealed the gas escapes into the boot
where it will rise extremely rapidly to the highest point and escape through
the nearest gap or porous material. If you don't have an isolator switch
fitted which gives you access to a battery connection point outside the
battery box you will have the cover off and so the gas escapes into the
boot. It is extremely unlikely that enough hydrogen could accumulate in the
boot to be of any danger. Trying to contain hydrogen is like trying to
carry marbles in a string bag. Nevertheless, I would charge a boot-mounted
battery with the boot lid open.
Regards,
Warwick

Subject: [ROVERNET - UK] Battery Charging, in or out of the car
All,
I recently had to purchase a new battery. Not because my old one was worn
out, but because it had been in and out of the car so many times to be
charged (too much sitting in the garage and not enough driving), that the
constant removing of the negative terminal had made the lead post turn into
a conical shape. As a result, tightening the negative terminal meant that
the terminal climbed up the post and off the top!
Anyway, why shouldn't I charge the battery in the car and leave the positive
and negative terminals connected. Is this a potentially dangerous thing to
do, and is there any danger of damaging the modern radio/cd player that I
have fitted.
For info, my new battery is of the fully sealed variety and is mounted in
the boot.
Many thanks,
Brian.

Just realized that I didn't point out in my previous reply that I was
referring to a conventional flooded cell, open lead-acid battery when I
spoke of occasional deliberate over-charging; not a low-maintenance "sealed"
battery or gel cell. Follow the manufacturer's recommendations in the case
of these.

Great picture Eric, thanks. The other post said that it was not a doughnut
also. Your picture clarifies everything. They are indeed different,
including the linkage for the float needle. I did confer with one of my
expert references today, who had been factory trained on the Rover 2000. He
did not remember that the floats were different and could not find a
reference showing the difference. I will share the picture with him. I have
learned more than my fair share of things today.
For reference, it seems that Moss has just one part number for Gross Jets
for HS carburetors. They also carry those .015 shims that go under the
needle assemblies if they are needed,

Hi Kent
Thanks for your note re the sunroof - if it is a factory installation, well
done because it will have been finessed rather than butchered in to
position.
I've noted also your comments on the 700R4 conversion, thanks, my
investigations are continuing, and I'll look forward to your advice on the
adapter plate.
Having driven 500 km now in my P6B with its new (rebuilt) 3.9 engine, it is
beginning to free up and I can feel this urge (in the motor, not in my foot)
to keep on revving.

Hi Folks (maybe Slats?)
I have two carbs here that I'd like to
identify both SU 1 3/4 inch AUD 280 and AUD 256 number might be wrong on the
second one as its hard to read.

Ben,
Had to go to one of my two local experts, but came up with the answers. The
AUD 280 will fit an Austin MAXI MK II 1800 1968-70 or a 1968 Austin Marina.
With the manifold it would probably also be a very good replacement carb for
a rubber bumper MGB to replace the Zenith-Stromberg. The Aud 256 is off of a
1967-68 Jag 240.
Hope that helps.

You can also purchase a very slow charge battery maintainer from Harbor
freight for about $7 on sale. this will keep it up with minimal danger of
over charging. Great for cars that do not get driven regularly.
