    LPG problems.

    Ok, not only am i starting to go grey but i'm about to pull all my hair out over my bl@@dy car. I replaced the twin carbs on the rangie with a 350 holley for ease of tuning and to fit a better gas system, now i have done this to my other rangie and it ran like a dream. Now i have fitted a sprintgas new gen mixer on top of the holley and i cant get the bastard to idle no matter what i do, i have adjusted the mixer plate height to the recomended height, fiddled with the power valve, sensitivity screw and the carb idle adjustment to no avail. Now i have noticed that if i tap the converter while running the tune changes, so could i have a dodgey converter ? its a LG motor gas P6 and is about 6 weeks old with almost no road k's on it, i really need some help here as i am about to break something expensive. The previous conversion i did was using impco gear and that was dead easy - i still have it so this is my last resort.

    thanks,
    Nick.

    Unfortunately, there doesn't appear to be an Australian LPG forum. I frequent this one:

    http://www.my90.zenwebhosting.com/cgi-bin/...s.cgi?pg=topics

    On this they have created an Australian/New Zealand page but there's almost no posts as yet.

    On the Newsgroups, there is this but I can't post to it as it doesn't appear in the list of newsgroups on Optusnet:

    uk.rec.cars.fuel.lpg to which I have read access through the server 194.69.207.134

    Does the converter have an idle mixture adjustment screw that you can try playing with?

    Yeah, it does but it only seems to adjust the enrichment of the idle not the idle speed.

    Does it idle on petrol???
    If so its the gas, if not its the carby.
    My first reaction to your problem is that the idle speed is set by the carby butterflys, even on gas, as this sets the air volume. Then the mixture is set either by the carby or the gas mixer. Now I know nothing about gas , but that seems logical.
