    HHO on a carbureted engine

    What do I have to do to a carbureted engine so that I can benefit from HHO?

    Like the air to fuel mixture, do I have to adjust it or will it self adjust?

    Which vacuum line?

    I would think that with a carburetor engine you would have, by far, the easiest job of all of us. The fuel/air ratio is set by the size of the jets, so you won't need to adjust for the computer playing with the mixture. From what I've read, you may need to adjust the ignition timing.

    To be safe, you need to be able to monitor your exaust gas temperature. When you start decreasing the amount of fuel, your engine will run hot, but the addition of hydrogen will offset that effect. So basically, you need to lean your fuel down probably by 10% or so, then add Hydrogen and measure the EGT. If its still safe, then you can attempt to lean the fuel a little more. and so on. You need to know how to put smaller jets on your carb and know the safe parameters on your engine. I am sure someone else in these boards has better more detailed information than I do.

    just don't forget one detail : if you are running too lean, because your HHO is balacing that, and your HHO unit stops working for some reason, and you keep your engine running, you can destroy your engine ! so, keep it in safe levels !

    There are about 358 different carburator designs. What car, engine, carburator?

    The only thing you can easily adjust is the idle fuel. Normally tightening the screws 1/8 to 1/4 turn will help with the idle air fuel. The main fuel system is controlled by a jet (exactly sized hole in a brass screw) and some have rods that go thru the hole. Then there is the transition circuit to enrich the air when you are slightly accellerating. Some have extra venturies that are used for full power. Your best bet is to get a manual. Some carbs are easy, some moderately hard and some are pure distilled evil.

    It either a quadra junk or holly, unless an aftermarket was installed.
