Hello everyone, I bought me a nice 1968 Chrysler New Yorker with LPG system. The Dutch salesman also knew about it so well, I don’t have printed instructions, on the net I don’t find the right one, therefore I hope that someone can give me tips on the correct operation. Short to me, 55 years, from the car area, but with gas so far nothing on the hat. I just want to say that I know how a carburettor works and what the Venturi effect is… The basic function of the gas system is clear to me so far, only with the correct operation haperts, since I never had a gas car. In the interior I have the control panel, see photo. Left gas, right petrol. I suspect that each electric valve unlocks the gas or gasoline supply. In MIttelstellung probably both closed. In addition I have a retrofitted train, which I have to pull when I drive with gas (or was it vice versa?) I make the days carburettor r I don’t know whether I can/should start directly with gas or first with petrol and only then, when warm drives, so that evaporators are heated, can switch to gas (according to the Dutch I could drive with gas) In Youtube videos I saw that you should drive from petrol to gas first carburettor empty before switching to gas. But that would mean n that engine runs out and you have to restart, and that during the ride ? Or do I have thinking errors in there ? How is the exact procedure when switching off on gas and unconverted when switching back on petrol ? Does someone know good links, whether text or video, where that is well explained ? ( unfortunately found nothing suitable) Then another question, does the tank have an automatic filling stop at 80% ? On the control panel, the green scale, is this a kind of tank clock for the gas tank ? Is there on the rig Is there anything else I need to consider, especially in terms of security? I really thank you for replies Best regards Gerd
