    It is really helpful for those of us who try to give people answers.

    And, welcome. Don’t mean to sound like an old fuss budget, just trying to keep things simple.

    Brenda;

    If you can run it (if you can) until it warms up a bit, does it run better then? After the engine has run for a few minutes, there are two hoses about 5/8" in diameter going into the out of the top of the carb. Feel these - they should be getting warm. They pass hot water through the automatic choke. As it warms this area up, it turns off the choke.

    Sometimes the choke mechanism on the outside of the carb can get fouled and needs cleaning up by spraying it with WD40 or brake cleaner... once the automatic choke is off, it should run normally if indeed the choke is at fault - could take a few minutes for that to happen. Mine would only run on two cylinders when the fuel filter clogged up. I'm not sure where the filter is on a Carry.

    There are a number of other things that can cause misfiring or "stumbling" but it sounds like a choke issue on start-up...

    It will run after it warms up until I stop and idle then it starts to sputter then dies and will not start again. I’ve changed fuel filter We removed the air filter and sprayed carb cleaner in it The new plugs were removed and cleaned because they get black on the ends after it dies. We also tried sea foam in the fuel. We’ve become very disgusted but continue to try to find a solution. Thank you for replying. It’s greatly appreciated

    If the plugs are black, it's probably a sign the mixture is too rich, which could be the choke staying on too long or even staying partially closed. Make sure the choke mechanism on the rear side isn't fouled with dirt or debris (somewhat common on these). Then take off the intake plenum into the carburetor to expose the choke butterfly. Start the engine - if cold, it should be shut or mostly shut. If completely warmed up, the hoses talked about earlier should be quite warm and the choke butterfly should be wide open... if it isn't, that could well be your problem, and something is causing the choke mechanism to hang up. Others here have more experience with this "melted wax" type of choke and how to service it. Anyway, give that a try and get back to us. I don't have a Suzuki, however I'm assuming (hopefully rightly) it will be similar to my HiJet...

    Don't give up; it's probably something quite simple! I wouldn't worry too much about the plugs - unless they are oil fouled, they will probably clean themselves up when you get the mixture right.

    There is a thread titled Choke-idle is too high in this sub forum that explains it all pretty well. It's old so way back but very informative.
