Got these sent down from the UK and had a chance to play with them today, thought i'd post my thoughts up.

Colortune

Wonderful to use, so straightforward it's awesome. Plug the spark plug in, connect rod and lead and you can clearly see the spark ignite and the colour. I was a little in the yellow so I leaned it out 1-2 flats till it was just bordering blue and left it at that. Not a dramatic change but I guess that's because I had it roughly in the right place to begin with.

Eezibleed

Ok this wasn't as straight forward.

Everything in the pack works fine however i've got problems with the caps and will probably need to make some up. I tried my clutch first, the smalles cap included did fit over the clutch reservoir thread, however it didn't turn nice like the actual cap (is this a metric/imperial thread size issue?).

I connected up my spare to the system and noticed tiny tiny amounts of fluid were coming out the top of the cap on the reservoir. I figured it was either because the cap was the wrong thread or 20psi was too much? (that sound right?)

It was the tiniest trickle and wasn't enough to trickle down the cap onto the reservoir and actually seemed to stop (?) after a while. With this I loosened the bleed nipple at the slave cyl and let it flow a bit till it was solid liquid running through the pipe and then tightened.

Pretty straight forward, tested onthe road and the pedal was firm like after a new bleed.

Now obviously you want caps that fit 100% properly, my only worry is the seals? The manual does mention you can use the cap on there by drilling a 3/8" hole through the top and then fitting a blanking plug when your done.

How well is something like this going to seal? There's two nuts that you tighten on each end of the cap to secure the hose in place (has a one way valve on the reservoir side). Is the seal actually dependant on the black rubber inside the cap or the nuts themselves? The inside nut was a bastard to tighten with the rubber seal inside the cap I mightnot have done it up enough.

Overall i'd definately reccoment the colortune, the eezibleed seems to work in theory, just need to test it with proper caps.

What style of m/c do you have? Some of them have holes in them so they can vent, so if you put a fitting through them they'll leak out the vent.

I have a colourtune, its fun and looks nice, but it really only helps with the mixture at idle, you can't use it under load where you really need to get the mixture spot on. It won't help you much if you haven't got the correct needle to begin with.

That's true, but needle selection is only going to be relevant when doing any sort of major changes to the engine, not when giving it a tune. Needle selection is something you should really only undertake on a dyno.

That's where the colourtune pays for itself -- assuming you have the right needle in the first place, you can get the idle mixture absolutely spot on which then guarantees that you have the right mixture throughout the rest of the rev range.

Agreed though, you've gotta have the right needle

Has anyone used an Eezybleed with the Oz-style (large diameter plastic reservoir) master cylinder? How'd you do it?

This is the brake mcyl i've got. Not sure if it's OZ or UK.



Anyone know what size thread the res cap is? I'm def not going to drill the original but if I can find the same size cap at supercheap or something that'll help. Or failing that a drive down to the mini places to see if they've got a spare I can use.

That's the one I've got on both brake and clutch. AFAIK it's the Australian one, I'm sure someone will correct me if I'm wrong.

My understanding is that the Gunsons kit doesn't come with a cap to fit this master cylinder.. is that correct?

Yep. It comes with four caps, 2 smallish ones and two largish ones. Largish ones being about 3/4 the size of that reservoir cap size.

You don't know the size of the reservoir cap per chance?

Nope, I'm about 2000km from the car at the moment so I can't even check for you Anyone else?

Yea its a PBR Australian made MC. The UK equivalent would have been made by Lockheed.

Iiiinteresting, from memory I think mine (6/1970 Mink K) has Lockheed on it.

Off topic, but does anyone know if this MC is suitable for discs or should I look at replacing it?

I used one with Cooper S discs on my old Moke without any problems.

Not quite right. It can be done under load. Vizard and at least one or two other people has written how to do it. (Got the articles somewhere) Without the all the details and safety aspects and driveshaft angles, etc, the very, very bottom line is jack the front of the car up, start it running then use the brakes to put it under load while pushing down on the accelerator to keep it from stalling. Done it a long time ago more than once. It works.

There's the other "under load" test where all you (very basically) need is a pencil in the carby piston but I haven't tried it yet. Got the book, sounds a great idea, very simple and costs nothing. It shows you where to modify your needle to whatever your engine wants it to be. If the needle can be modified that far which would generally be true as your standard needle would require more enrichment that leaning out if you've modified the car. But my wife says I'm constantly wrong so don't take my word.

I have an ezibleed, we bled Rodney's brakes twice with it recently.
First time was a bit of a disaster, let the pressure drop too much in the spare was one thing. Could'nt get a cap to fit right so we drilled a hole in the original which would have worked fine except that we forgot about the vent hole
After mopping up even more fluid from that I successfully closed the hole with a very small nut and bolt.
Our 2nd attempt was great, two spares, no leaks and had the whole car done quite quickly. Oh and Rodney had got another cap to fit afterwards.
As long as the brass unions were tight, it was fine.
I'm uprating the calipers on my car soon so I'll be using it again.

Right then, tommorow i'm popping down to find a replacement brake res cap and giving it a go .

Shard

Let us know how you get on. Don't forget to keep both reservoirs topped up.

I've had an Eezibleed for a few years now and they are great. My original packaging etc has well and truly bitten the dust, but I'm sure I remember seeing a max of 10psi written somewhere. I've always used it with bugger all pressure in the tyre and had no problems.



These MC's were fitted standard to the Clubman GT, so yes - they are OK for discs.
