Vacuum for brakes
I think you have to connect with a pipe that hole to the servo brake if your car is 89 on or at least close that hole. Do you fit the little pipe that goes from the carb to the distribution unit? I hope I can help Stefano ITALY

Vacuum
Hi, Theres no vac advance on a weber manifold, because it just wont work. The vac advance gives you better fuel economy on light throttle. You need to buy either a moddified dizzy with no vac and to suit your engine mods, or go for after market mappable electronic ignition such as Omex. Got the Omex on mine, its excellent!!! As for the servo vacuum fitting, I cant help you as mine was already fitted when I got it. Cheers, Gavin.

vacuum pipes
I had the same problem with my SPI 1993 coop, and a mate of mine had it on his MPI like yourslf both of us found that the faulf lay in either a blacked vaccum pipe in my case or the vacuum from the ECU going to the wrong place in his case so just check the pipes are clear of blockages and dont leak before you go buying sensors!!! I made that costly mistake.. regards Mark

Vacuum pipe
I have the vacuum pipe connected from the distributor to the thermostat housing and a joining pipe to the offside carb. Do you think it could be something to to with the ignition? My local Mini centre said it could be the coil or maybe HT leads but I really dont know as its fine until about 3000 rpm and then the engine just goes crazy. Hope someone out there can help. Many thanks.

The only thing i can think of is vacuum. Have you tried to crank the engine over with the air filters off the twin set-up?

Fitting vacuum gauge
Hi,
I have just brought a vacuum gauge and to fit it the instructions say to screw in the adaptor into the inlet manifold! they say that some inlet manifolds already have a hole for this and is blanked off! however i cant find one on my mini. i was wondering if anyone else has fit a vacuum gauge and if there is a hole or do i need to drill one myself, and if so how would i go about doing this?
My mini is a mini 30 998cc single carb!
Thanks!
Dan!

Dan, I fitted a vac guage about 20 yrs ago to my first mini. The fitting wasnt screwed like you say but barbed, ie a series of steps of smaller diameters on the fitting. A bit like a hose pipe fitting. The idea was to drill a hole about the size of the middle diamater then tap the fitting in, the mainfold is ( or was in 1980!) cast iron and fairly soft. The drilling of the hole is a tricky one as you do not want any swarf getting in. The best way is to remove the manifold, I did mine by drilling with the drill bit loaded with grease, being cast iron the cuttings are little chips and stick to the drill bit. It follows you have to be very careful, some of the later maniflods may be water heated?? in which case you have a problem, though I am not certain about this. You say the fitting is screwed on then you will have to drill and tap the manifold, almost certainly a removal job. Have you considered tapping into the vacuum advance pipe to the dizzy? Just a thought The good news is a vacuum guage is a fascinating device! Good luck

The simple solution, a carb spacer with the vacuum adapter provided. If you get tired of having the vacuum gauge, the adapter comes with a screw which effectively plugs the adapter. http://www.minispares.com/Product.aspx?pid=34395
Or, if you've got a ½" thick alloy carb. spacer, you could order p/n 070.350 from Holden Vintage and Classics, drill your own hole in the side of the spacer, tap 2BA threads and wind the vacuum adapter in - I've done this and it's not bad at all. If you get tired of having the vacuum gauge, the adapter comes with a screw which effectively plugs the adapter. It requires a threaded hole (Use a 2BA tap) for fitting into the carb adapter or manifold to make a vacuum connection.
Cheers -

Thanks for your help! i dont fancy having to drill in the inlet manifold so the idea of the spacer i think is good, so ill try that!

MK1/2 Brake Servo Vacuum Fitting
Hi There,
I just recently purchased a Mk1/2 brake servo, 21A1293 and really need to know what thread is in the body for the vacuum hose connection. I thought it was 3/8 bsp so bought a hose tail fitting to screw in but no go. Thanks in advance.
Richard.

Vacuum hose
i have just put on a crankcase breather on my mini and there was a pipe from ther carb to the crankcase, there is no where for this pipe to now connect to.
do i just leave the pipe off altogether or not, just concerned as there is a short pipe off of the left hand side of the carb now exposed.
Thanks

Blank it off, or car will run far too lean, and rough!

I have found out that this thread is 5/8 UNF, are these fittings available?

Hi, this may seem like an odd question, but why did you fit a beather filter?
If it was for cosmetic reasons then I'm afraid it will bite you back for it as your engine bay will quite quickly get covered with a film of oil. This will burn off in the hot places making the cabin smell quite badly of oil smoke and give you a sore throat on long journies.
If it was to take advantage of the very, very slight increase in performance, then an oil catch tank is a much better idea as the oil stays in there, not coating your engine bay.
I've plumbed mine back into the carb on my race car as it's just not worth the mess the breathers made even with a catch tank.

i was told the performance would have a slight increase. it was advised to me because i was getting a few ideling problems and someone saud thay had put a breather filter on and it solved the problem, which so far it has. not too keen on the fact the cabbin will start smelling of oil.
thank you for that reply.
i have had the jet replaced on the carb and my car has a stage one kit with 1.5.1 roller rocker as well, do you have any sugestions on how to cure my ideling problem, as in if i leave the car for more than 30sec ideling the engine just stops.
Thanks again
