Questions & Answers

  • What size pump nozzle does the TM--40 come with? I just want to make sure I'm buying the right size nozzle. I love this carberator and hopefully it doesn't come with the smallest pump nozzle cause if I can lean out the pump some,this is no doubt the best carb on the market.If there is any info that you have about cutting back on the pump spray that could make it run better as far as changing the main or pilot jet when I change the nozzle please let me know. I had to go down a few sizes on the main jet cause it was just to much fuel but it's amazing how much stronger it is jetted way down than the factory carb and jet had. I feel like I'm running lean now when running wide open in hi gear but I had to cause it was just about to foul the plug with the jet it comes with new. I know it's a little bit big on a 400 ex but it's a different 4wheeler with the tm-40 on it if I can dial it in just a little more. I look forward to hearing back from you.

    The TM40 comes from the factory with the largest accel. pump nozzle installed (size 70). On a 400, you may want to go all the way down to the smallest nozzle and see how it does for you. There is also some adjustment on the carburetor. You can change the throttle point the pump is engaged. Sometimes it helps to delay the spray a little bit.

  • Is there a way to some how controll the amount of fuel that the pump sprays,like possibly a jet inside the carb where I can cut back some of the fuel that the pump squirts ?
    I realize that you can adjust how soon or how long you want it to spray but I need to some how to lean out the accelerater pump if it's possible. I also realize that the carb is just a little bit to big for what I have it on but when this thing gets good and warm,you better hold on good cause you are getting ready to go for a ride.
    I look forward to hearing back from you.

    Yes. You can change the size of the pump nozzle, to reduce the amount of fuel. For most of the applications we pre-jet pumper carbs for, we drop the nozzle down to the smallest size, which is the TM36/43-A. If you do this, you may want to pick up a N124.063 o-ring, as they can easily damage when being removed from the old nozzle. When you install the new nozzle, pay attention to the alignment of the nozzle hole where the fuel sprays out.

  • How does one remove/replace these AP nozzles?

    You can access the bottom side of the nozzle, by removing the float bowl. We use a small screwdriver to gently spin the nozzle from the bottom side, while putting slight pressure downward on the nozzle with the other hand, from the carburetor bell side. The nozzle is not threaded, so it will not unscrew. Spinning it makes it easier, but ultimately, you will be pushing it out through the bottom. For re-installation, you can use the same screw driver to seat, and clock the nozzle.
