    Default Max 5000 issues

    Looking for some help. I have two used Max 5000's that work consistently, and I like them. However, one throws marks 25 yards every time, the other only throws them 12 to 15 yards. I don't have a manual, and can't find one, so anybody out there have any idea how I might get the short one stretched out to 20-25 yards? I just figured someone has had this issue and would know how to fix it. Thanks for any info you might have.

    Does this happen with all bumpers?

    I have a few Max 5000 bumbers that have become rough on the inside and do not slide smoothly on to (and off of) the Max. They don't go as far as the other bumpers that are smooth inside.

    Maxx 5000 uses a valve system and cams to meter out 02 and propane, if valve is clogged or cam is worn you may not be getting a full measure of either making for a smaller kick when it is ignited.

    Default Try

    I used the Mapp gas ....but you can try a little more O2 on the regulator.Turn the diaphram screw in Clockwise one turn at a time.....that will give you a bigger bang

    The first and simplest thing to look at is the ignition timing. When the things are disconnected, look at the machine from the front. Specifically look at the bottom center, where one of the cylinders sits over the combustion chamber. The opening of the combustion chamber should be off-center in the cylinder--the cylinder should have moved a little bit past the centered position. As you look at it, the opening to the combustion chamber will appear on the left side of the cylinder.

    Compare the one that shoots farther to the one that shoots short. If you need to adjust it, simply loosen the two nuts that hold the rotating disc, and rotate it to the proper positon before tightening the nuts.

    Jay, are you saying that using MAPP gas gives longer throws than Propane?
    That would be very cool !
    I have 7 Max 5000 and found so many things that can affect the throw.
    The ones listed are the most common, with disc position being #1.
    I have had spark plug gaps too large, bad coils, bad micro switch (the one that controls the coil), bad condenser, bad coil wire, bad Propane regulator.
    If the disc position is correct, then I would check the valve operation.
    This can get to be a very fustrating experience, but there always is an answer.

    I have been searching for small electric valves to replace the manual valves, anyone know where those can be found?

    Got it worked out. It was a timing issue. The good one fires and stops centered over the chamber. The one with issues fires and then travels another 3/4 inch. I loosened the nut and rotated the drum 3/4 of an inch to compensate and it's working fine now. Thanks for the help and information.

    Another question. You can use Mapp gas instead of propane? How does that work? Just curious.

    I know the MAPP gas will work in the new Thunderbirds. Not sure about in the older Maxx's
