new or old?

try chris perfect, good kits, for new ones.

I think...

Hi Austin,

I know of Chris Perfect & most of the others :-) I was sort of fishing to see if anyone had one kicking about for a bargain price ;-)

If you find more than one kit let me know ;o)

There's a ised IWEMA kit on eBay at present, without a bid at GBP200.

Single tank, I'm afraid.

Have bought said kit for £200 pounds (

. Haven't paid as yet. Do you think I've made/making a mistake. When I go over for it has anyone any advice etc...

Thanks

Graham

Take the vapouriser apart and check that the rubber diaphram isn't perished perhaps? I can only see one mixer in that bundle but there's no doubt a second one somewhere. You've also got a vacum gauge - and the iwema vacum operated closed loop thingymajig. It's always a bit suspicious when kits are pulled out of vehicles for no reason - they're not even pretending that they stuck a diesel lump in instead....

Thanks for that.

The story goes that the vehicle that it was fitted to was written off and scraped, so he is selling any of the bits that were worth salvaging. He has other parts off it on e-bay. Whether or not this is true, I don't know. Shall have a look.

Thanks for your Help.

'bout 600 quid for a new one the same - it appears to be the one sold by Chris Perfect. The vapouriser is an OMVL.

If you want tuning or installation instructions, lemme know, I've got 'em here somewhere.

the orange plastic gadget is an "Ecomax", vacuum operated. connect a vacuum line to it before you install it and make sure it works - the flap inside should rise up when there's lots of engine vacuum. In use, this slows down the gas flow. This means that you can tune the basic setting fairly rich so that it pulls well at full throttle, and doesn't go lean, yet not waste gas on over-run or light-throttle slow running, when there's more vacuum. This is a problem with simple open loop systems, which the ecomax goes a good way to solving.

I had the spring break on one recently, luckily I have a spare. 's only a simple coil spring though, which will be easy to replace.

Interesting point from this recently. To tune these things on a Crypton machine, you disconnect the vacuum from the ecomax, so that it doesn't do anything, adjust the basic settings for idle and at 3000 rpm. Typically set the 3000 rpm to run about 1.5%-2.0% CO. Then you connect the Ecomax, and tune that to get the best mix of low CO and low HC.

So I'm up the garage to do this, and that's how I discovered the broken spring, ecomax not doing anything. Thought "bugger", came home. The next week, the electronic distributor amp unit packed up (bastard thing, 's only about a year and a bit old), so I had to go back to the old-fahioned points distributor. I also fitted the spare ecomax which I had in the shed, having checked that it was working first (brain was engaged, for once).

Back up the garage, tuned all nicely, which in this case meant about

0.35%CO, and about 150 HC at 3000 revs - not brilliant, but OK - a really good one should come down to about 0.2% CO without putting the HC up.

BUT. 2 weeks before, (having not changed owt else on the engine) I'd got the idle emissions damn-nigh perfect, to the extant that it'd have passed the BET cat-test, which I was pleased about, as it indicates a good engine. With the point ignition, I can get the idle figures well within the requirement for the non-cat test appropriate to the vehicle, but can;t get them as good as previously. So I guess there's something in this electronic ignition malarkey after all...

Well I've bought and collected said kit. It was complete and as far as I was able to tell, genuine. Just hope it will be ok. Just got to fit the bloody thing now.

Graham

Did you get the free puddle of water with it too ;-)

Good luck :)

when you fit the vapouriser, take the gas outlet from the bottom outlet, not the top one. This will stop it accumulating heavy ends.

Thanks Austin, will try to remember that. Won't be able to get to it for a bit. Have a wedding to go top and some oil seals to do :o(

there's always something.

put a bit more petrol in the (dual fuel) car the other day, 'cos I was going up to the smoke with it, and discovered that the tank has decided to leak along the seam. git. Another fun job waiting for a fine day...

Everytime I get into her I notice another one of those little jobs, oh well the joys of owning a landrover and all that. Mind you, the rate I seem to be getting through petrol at the minute, the lpg kit is quite high up the priority list!

Graham

No that cost extra.

Well have been in touch with Chris Perfect who supposedly sold the kit. He got back to me yesterday: He had sold the kit, it was fitted to a 110 v8 by said chap. He said it was and still is the best kit in his opinion that can be fitted to a carb v8, it is the same as the one he runs himself. When he sold it to the chap it cost £850! The kit is complete and in good working order. Chris Perfect is sending me the relevant manuals relating to it and a service kit. It all sounds very positive, so fingers crossed it should be good.

well, I run one of his kits on my 110, no complaints.

I did have a spring break in an ecomax, but that could happen to anything, and it's done quite a lot of miles.

Thats reassuring, thanks Austin. I think it should be ok. It is very complete, every grommet nut and bolt is present, which suggests the owner was quite careful. I felt better that his story checked out.

you can check that spring... if you unscrew the top of the ecomax, then the flap inside should rise - look through the hole where the pipes attach. The top bit is the vacuum unit and presses down on the flap - when vacuum is applied, the plunger gets sucked in, and the flap springs up. If it does, you've not got a problem - Chris told me that he's not heard of any others breaking, so i reckon it was just random bad luck. I can easily enough find a spring to replace it, I daresay - I had a spare unit, so it's not a problem anyway - and the vehicle still runs with it not working, just adds a tad to the fuel consumption. Interestingly, it makes a difference to the way it drives - more engine braking with the Ecomax working.

Thanks, I'll have a look at that.
