Vehicle takes several tries to start when cold and will stall at idle until warm. Whilst driving, power is lost when accelerating out of corners. Carburettor is a Bendix Stromberg. Smells of fuel and may have a slight leak. Image below.

Is that idle shut-off valve working properly?
Looks like that rectangle bit in the centre of the pic should have some sort of cover on it?

No idea, only picked up the car on Friday. Just looking for a quick fix until I get my 350 Holley, adapter plate, and throttle cable.

I run the same carb on my daily, and please don't ruin it by putting a 350 holley on it, the strommys are a great carb,
all ive done is put a kit through it and no problems, cold start for me is 3 pumps of the throttle, and hold light throttle and starts straight away, than idles at 500-600 no matter what temp

Do you know what the carb or engine was in originally? The later (HX and after I think) engines with emission controls had a very lean calibration that coughed and farted at the best of times. If it's one of these you'd be better to swap it for a HQ era carb or go straight to a new manifold with a Holley or Weber.

For goodness sake don't use an adaptor. You would have the air of a 2 barrel carbie being stuffed in a tiny single little hole in the manifold. If you get a Holley, get the correct manifold.

The carby has a manual choke and the vehicle looks as though it never had one, as I see no holes in the dash where they removed it. In other words there's no cable connected other than the throttle cable, so I can only operate the choke from the engine bay. Would this vehicle (UC) previously have had a carby with an auto choke, or is there a carby with auto choke that fits my manifold? (Choke lever in previous photo is directly centre-right of long spring.)

With the correct manifold, will a 350 Holley use much more fuel?
Part of my thinking to get the 350 Holley and nice chrome air cleaner now rather than waitng until I build a nice 202, was that at the moment I gotta put up with this eyesore... open to suggestions but that air cleaner is going in the bin right after I adjust it with a hammer.

No auto choke on 6 cylinder UC, I think the 4 cylinder sunbird had one, has this engine been transplanted, also what size is it. In the 1 picture it looks like 173, which can't be be UC

Heaps and too big for anything less than a 202

It looks like your existing carb is a late emissions-calibrated carb, an earlier model would run much better. If fuel economy is an issue the little Weber would be a better choice. You'd still need a two barrel manifold and adaptor. See this http://www.gmh-toran...6-weber-34-adm/ thread of Muzzys.

The choke for the 6 cylinder UC is left side of the steering column, as circled in red, The 4 cylinder may have had an auto choke, too many years ago to remember, someone else will confirm. Give the air cleaner a sand & a coat of paint, it'll look as good as new, you could even cut the snorkel of for a "cleaner" look.

Our 202 UC takes a minute or two to warm up and stalls the first time you try to move it when cold , your loss of power is that only when it's not running at operating temperature ?
UC's FTW!

4cyl starfire UC would have come with a Varajet carb with auto choke. OP's sig says he has a 1980 sunbird, which most definitely would have left the factory with a starfire.

Don't smash up the air can, that is not the problem,the 3.3 red label air can has the same fittings on the base,the "unused" piece in the picture was used on "emission" type carbs. and was held in place by a "special" clip.
The diaphragm on the silencer operated a "winter/summer" flap (eng. temp. sensitive) that was connected (via other shit) to the exhaust manifold by a piece of convoluted pipe to the "oven" on the exhaust manifold.
Either change the can to of these

or change the carb to one of these or the equiv. weber, both seem to have same prim./sec/ throats... parts availability pending.

or...The "leaner" type carbs as already said can be a bit of headspin,,,tried that on a 253 with "emissions" carb. very similar problem,put an old emissions carb. on...much nicer.

You could look at keeping the stock type air cleaner can and connect a flexable air hose to it and poke the other end out somewhere behind the grille and give your carbie, whatever you chose, plenty of cool clean air uneffected by hot dirty engine air from inside the engine bay.

I think a pod filter would do a better job in that regard but I'm not going for that look. Cheers.

It's not much good with those dents in it and the horrid mounting bracket seems to be damaged. You reckon anyone would want this and how much should I ask for it? Selling anything under the value of a block of beer is just wasting time IMHO.

Which model Holley is that?

Well unfortunately mate, I got nothing on that side and the other side operates the lights.

5200, it's a copy of the Weber built under licence. An actual Weber will be cheaper and much easier to find.

The dings don't look that bad in the picture?
Got no idea what can is off...some old holden...looks GTRish but could be wrong probably used on heaps of em.
When you say it smells of fuel...is that from the exhaust or a raw fuel smell from under bonnet.
Best identify the carb before going deeper...i knew some one threw up a list not long ago of applications somewhere
