Well, i should have admitted this earlier(i did read you were suppose to intro yourself) i have many old english sports cars, MGs,AHs TR3s etc
and of course they all need work/restoration.
Thats the fun part! over the years i have bulit an
English wheel, have purchased many other sheet metal tools like a Pullmax. I have also collected
machine tools like a Bridgeport, 3 lathes and lots
of tooling to make more tooling for the Pullmax.
Coming soon! the forge and foundry section. I
would not have believed i could fill up a 100' X
40' shed with tools and need more space but i did. Thanks for your time! back to the shop i go!

If you're a toolaholc, perhaps you have one of the gadgets for balancing SU carbs on the Rover V8. The repair manual calls if a Gray-Horwood type air flow meter. I want on to use om my Plus 8 Morgan. (Not that I NEED it, but you know how it is with these tools!)

I don't recall ever even seeing on of these.

I have seen that tool in the past, in the accessories catalogue of the MG Owners Club in the UK. I'll see if I can't dig up a copy!

Guys,
i have the venturi type with floating ball in a tube, is there another type????? i even played with this one and then tried with a hose so maybe
if i had too i would know what it should sound like, but have long since forgotten. it helps having a Sun 1115 engine analyzer too!
Hmmmm a tools i may not have? oh no!

Bill,
i couldn't stand i had to look it up in a Rover TC2000 service manual, and that tool is a carb balancer, using a center zero gauge(magnahelic)
2 hoses feed each side of the gauge from boxes
that sub for the air cleaners. so if one carb is set a little higher it has a higher vacuum(in the box) and the needle swings to that side. it shows no inches of water column or mercury, so its not calibrated, just an indicator. i could take some pics(2) of the manual and email them to you.
my email is tlthorne@apci.net

if you have the venturi type it should work ok
good luck!

wishing i had a morgan!

Toolaholics:

Thanks for the offer to send a picture of the Rover V8 SU balancing. However, I already have a picture in the Haynes Rover 3500 manual, which is what prompted my question.

Steve said he might locate one in an MG catalog; that would be interesting.

I do have two of the conventional airflow measuring devices, but it is a bit of a trick on the V8 to check both sides when you're working alone.

Now, a man with three Bridgeport lathes should be able to make the equivalent to this gadget!

I have another question about using oxygen sensors on these old cars. I'll make a new post for that.

Bill,
a center "0" magnahelic gauge is 50$ in the Grainger catalog, if you have the venturi type
with ball in a tube, you could take the tube off
and add vacuum line to the meter. probably the
need some type of a simple clamp to hold it
to the carbs, those boxes probably bolted on.
i wonder how accurated it would be as if you move
a few inches one way or the other, you have a different view of the meter. probably you are getting fairly close with your gauge that only
your sparking plugs know its off!

take care!

I finally found the catalogue I was searching for but the tool isn't in there. I must have seen it somewhere else and then assumed that it must have been in that publication. Rats! Sorry.

Steve,
Thanks for looking. If you come across it later, I'll probably still be interested.

TT,
Thanks for suggesting a source for the gauge. I'll try it when I get ready to do the fine tuning, i.e. keep it running without constant attention.

Thanks to Dave Russell and this forum, I have found what I think is the correct replacement for the gauge on my Gray Horwood Synchronizer

It's a good forum... not used as much as it should be.
