There's loads of info on this in previous threads, the one to get is the MG Metro HIF44, using a TitanMotorsport I/L Manifold, and K&N filter.

John, we dont hear much from you lately, how is Oz treating you both?

Brad, NOT HELPING ARE YA how's the muddied water up in Caledonia

Bill sdgpm

Just offering an alternative, i don't like SU's much.
Brad (Sprite IV 1380)

Wow

I couldnt tell

so thats a tenner, off a scrapyard Metro, thirty for the manifold


or 500 squids for the webby

(not that I wouldnt mind trying one against Gary's new megaAseries next weekend, but dont tell him)
Bill sdgpm

Not 500 quid, but it is expensve with jetting & RR sessions.
However it's worth it for the induction roar :-)

Hi Brad

You can make a similar noise by snorting up your throat/nasal passage with your mouth closed, apparantly...

DHLA is a dell'Orto not a Weber

Someone appreciates you spelling dell' Orto properly, David (though the company may have switched to 'Dellorto' in the 1970s to avoid looking too pedantic ...).

Eeeeee (from Heckmondwyke!):

The HIF is the ultimate - the most developed - form of the SU carb. It has a concentric fuel bowl which can prevent fuel starvation problems in some situations. But the early ones are the best for our purposes - the later HIFs were encumbered with emissions add-ons.

HIF44s are just absolutely lovely. Very classic SU behaviour and delivery but very refined. Also once you've done a bit of work to them you can get a little bit more out of them which can prove rather useful when you want some serious induction :D

Webers are seriously throaty but they are complex, relatively expensive to set up and can spit to an extent if you're poodling around traffic.

Is it really that simple.
Sorry for my ignorance but the intricacies of carbs has always baffled me. I haven't been able to get my 1967 1275 running properly since I rebuilt it a few years ago.

Is there anything else I need to know or other threads to read. I've done searches before but get lost in discussions about springs jets and needles.

Thanks

Do yourself a favour and get your car to a rolling road (aldon maybe)The money will be the best you have spent on your car.

I'm in the process of gathering the necessary parts to build a fast road (high performance) engine. Carburation is one area that I'm still unclear of. I've read the above responses and unfortunately here in Canada we don't have access to alot of used carbs and manifolds that will fit the 1275 or "A" series engine. What was the HIFF 44 used on and does it matter whether or not it comes from a single or double carb set up?

Steve
C Roode

Steve the HIF44 was used on lots of cars, but the one most commonly used came from a 1275 MG or MG Turbo METRO. The 1275 later Minis used it too until they changed to injection.There are quite a few twin carb set ups using them, but you would have to mess about with the cable linkages a bit more as they are left and right handed.
Colin, do as suggested by Carl, take it to a decent engine tuner who has a rolling road, and experience with A series engines, they are getting a bit rare now though. Money well spent.

check around with some old hole in the wall british shop, that have been around for the past 50 years, most likely you can find something in a shoe box somewhere.

Anthony any chance of a youtube video?
Brad (Sprite IV 1380)

Tempting... but easy enough for anyone to make the correct noise. Similarly, almost anyone can make the 'Morris Minor slowing on the over-run down a gentle slope'.

Car noises used to be so distinctive. When I was small, we (living on a hill) used to guess the make/model of each car going up or down.

Morris Minor, Minis and MGBs were the easiest.

Happy days!

now you're talking

When I was a lad (I'm sure there's a joke there but I am far too creaky to enjoy it nowadays) the Brummie coppers were just getting their first Austin 1100 panda cars. (support local industry)

These had higher number of fan blades than the standard 1100s and it was common knowlege that the local villains could hear the rozzers streets away, knock off whatever skullduggery they were engaged in and wait 'til they were past.

Happy days?
Bill sdgpm

You WERE a lad, Bill. You WERE.
Of course, it IS a joke, but it's one that I share these days, being only one calendar year behind you, and following your example to the letter (scrapheap, pittance, penury etc.)

My chum John Henderson and I used to walk up Lake Hill on the way home from school, and he could tell me the make of every car that came up behind us. If I could do that today, I'd go on the halls.

I am using a HS6 from a Marina and I am pleased with it. Just search yourself the right angle piece to level the float chamber and off you go. There is no Carb Easier then the HS. BTW the inlet is more important. The orto's and Webers only do outrun the HS or HIF 1 3/4 carbs above 4500 RMP so unless you are doing motorsports it isnt worth the bucks.

4500RPM, so that'l be every gear change then.
