Why is it confusing you that i can be away from the car and be 100% sure as to how things are with it? Does everyone have to be available with camera in hand to take photos prior to asking a question here? And if they can't be, the response is as above?
Tell you what, i'll forget that i ever asked ...

It still has the gauze-filled flametrap, then it vents to atmosphere. Very few Imp owners keep the rubber pipe connected to the airbox, it just hangs down and points at the deck, doesn`t cause this type of issue, if any, it helps it breathe better and doesn`t cause air filters to bung up 2 or 3 ...

It has a vacuum take-off for a servo, but this car has no servo so I blanked it off. The manifold is the correct one for twin SUs on an Imp. The dizzy advance pipe is connected fine. It`s a bit more than mega high, it`s like wide open throttle high! So, after all this, is it safe to say for definite ...

It`s got the original crankcase breather from the side of the oil filler neck which vents to atmosphere, not into the air canister. I`ve tried the method you mention, has zero effect.

Do all SUs have breather stubs? These don't.
The throttle butterflies haven't got the overrun valves. They're the type with none fitted.

Yes x 3! That`s why it`s so infuriating. I guess it has to be an induction leak, but convinced myself that extra air can only have one effect: a weaker mixture and things slow down? Not the case here, it`s possessed I tell thee!

There are no breather hoses for the intake system on an Imp, at least no perishable ones. I see what you mean though and I`ll recheck the fanimold.

Cheers!

Recently fitted twin HS2 SU carbs to my Imp. The carbs were checked and declared fit for purpose by a trusted long term user of the same SU setup on his 2 cars. The problem I`m having is getting the car to idle properly. All it wants to do is rev it`s head off. It has the correct jets/choke tubes ...
