Re: Advice please!

Yes, the actuator always closes when not running but opens up to the default as soon as it sees pulses on the rpm wire to tell it the engine is turning. Starting on a richer mixture than is needed usually is harder unless you floor the throttle to get as much air in as possible, so getting it right ...

Re: Advice please!

Power valve at 1/3rd open, start engine let it idle and look at the software. It will try to get the mixture spot on by adjusting the actuator but as the actuator isn't being used it won't have any affect. Adjust the power valve to get the actuator so it sits somewhere around 80-100 when the lambda ...

Re: Advice please!

If the mixer has been correctly sized for the engine airflow, it will be about right straight from the box. It might need the top screw adjusting slightly but not by much. If I remember right, one screw is marked Idle so you would expect it to be the idle bypass but that is wrong and it isn't (obvio...

Re: Advice please!

At 18 years old, I suspect unless it's been kept nice and warm and dry, the bolts holding it together will be seized in and at least some of them will shear off. In all honesty, rather than buying the overhaul kit then finding the bolts shear off or it doesn't cure the problem, I'd just put a new on...

The petrol system runs full group anyway on a Classic so that is what it really needs to be set to.

Re: Advice please!

Yes it will. You have an R90E Super rather than a R90E standard. The BRC one is capable of supplying way over 190 bhp despite what the spec says.

Re: Advice please!

The R90S is just the high power version of the R90E (strictly speaking, it's an R90E Super). The older ones used to come in two versions, the normal one and the high power one, the later ones are all the same and can run at far more than the 190 bhp they seem to quote. Nearly everything from Italy i...

Re: Advice please!

But as it doesn't currently run on petrol, that's not really relevant at the moment.....

You should have asked, mixers often come supplied with a power valve whether you need one or not so I've got at least two floating around and could have bunged one in the post.

Re: Help! How do I best foul-up my LPG/CNG gas conversion?

Looks like Simon beat me to it. Rather than being bad, a soldering iron, and the ability to use it, is mandatory, along with glue lined heat shrink tubing.

It isn't so much how to do it as understanding how it works so you know why you are doing what you are doing.

Re: Advice please!

LPG is more critical in fuel/air ratio than petrol but I wouldn't have expected it to not start. Once you get it right it might be an idea to drill it and wire it so it can't move.

Re: Advice please!

If you look at the diagram it will show the signal wire from the lambda sensor being cut and the signal intercepted. DO NOT wire it this way, just Tee the purple wire onto the signal wire and leave it going to the petrol ECU. Hopefully it is already wired this way. Only connect to one sensor too, th...

Re: New Mixer Ring

Do both chokes open at the same time or is it a progressive carb where one opens at small throttle openings with the second one opening when you give it some welly? If they both open together you can leave both the adjusters on the Y piece wide open and control the mixture with the single power valve.

Re: Advice please!

You seem to be over-thinking it. As far as the MoT is concerned, as long as the lambda sensor is flicking from lean to rich and back again at idle and also at open throttle, then you wont have a problem with the MoT. The mixture will be correct under the two situations it is tested at. It's also pre...

Re: Advice please!

I backed out the small screw a touch (just to see if I could see it's threads) and re-tightened and think it went in a smidge further than before. When I fired it up at idle the actuator was at 166 default position and O2 was rock solid at 0.5V. That stability vanished once it had had some throttle...
