The rangie has a bit of a bitsa system fitted.
With a BRC gas switch, but a couple of toggle switches which manually switch the fuel solendoids.
It also has a Kar-Gas (hungarian) reducer/vaporiser.
I think I have the main line valve right as it drives OK on gas, and I think I have the diaphram setting OK, as it doesn't go flat when driving. But I can't get the idle mixture set to make it idle.
I changed the plugs, but can't remember if I regapped them.
I tried changing the leads, but when I fitted the new set it wouldn't even fire never mind run on petrol so I put the old ones back. I bought a new dizzy cap, but haven't fitted it yet.
I've tried the idle screw in just about every position from max in to totally out, in half turn increments, and the best I could manage at idle was one small splutter but no hint of an idle.
Above 1k revs it runs, but let it dip any lower and it dies instantly.
Any suggestions.

I know you havent changed it yet but I would have a look at the dizzy cap and rotor arm, a stuck carbon brush or even just a worn dizzy cap could cause you know end of problems especially with LPG.
When you said it wouldnt idle did you just mean on lpg or on petrol as well.
Not related but I had a misfire on my old one once. It ran spot on on petrol, switch to gas and it would misfire like a curse word, spitting back through the inlet. Turned out to be a bad connection on the thw two wires that fed the dizzy. Wasnt enough to be noticeable on petrol but you couldnt drive it on LPG

on a v8 its hard to get the gas mixer the right size.
usually they are too small which means they can idle well but will restrict the top end...
if yours has a big un (ooo er missus)
then it might be lacking in a low idle draw through it... bassically its just a venturi like a carb and so the air doesnt speed up enough to pull the gas through reliably.
best to spend the money and get a variable venturi mixer its like a piston type thing..
ive used these on jags to great effect..
alternatively just go smaller on size and don't worry about reving it too much..
i have one to fit a rover afm if its injection. u can have if u want?

It has the normal 40mm mixer, the too small one.
It idles OK on petrol. Although some times a little low in drive, and high in park/neutral.
I'll try changing the cap, and regapping the plugs, if I can find my feeler gauges. Can't remember the last time I bought a set of plugs that weren't gapped perfectly for Petrol.
Going to check I have the idle setup right too.
It is an EFI A Rangie, and does actually drive fine. Not as "grunty" on petrol, but perfectly adequate. Let's face it, a 3" lifted rangie isn't going to be revved race car like anyway is it.
Oh, and running mainly on petrol, I managed to get nearly 14mpg mixed driving (about 60 miles being town) from about 180 miles this week.
