Does it matter if you remove the limiter screw to rev up your motor and gain a lot of speed. ( I don’t mean removing the governor) I just mean that screw to adjust the rpm at full throttle.
A couple questions

Perfectly fine. Many people back it out to get a few more RPM's
DO NOT REMOVE IT!
remove the air filter (for now)
back out the limiter screw and open the butterfly with your hand until fully opened up;
(looking inside the carb while doing so and you'll know whn fully opened!)
then retighten the limiter screw so that you cannot move past that point
which would be closing the butterfly in the opposite direction anyways..
instead you'd bend the butterfly shaft and ruin the carb
(that's what the limiter screw is trying to prevent)
Now put the airfilter back on and you'll be good!
That way you can be sure to have all the rpm your engine and setup is capable off while still being sure you don't accidentally snap the cam off or bent the butterfly stem.

There is a permanent stop on the carburetor to keep the butterfly from opening far enough to close. He's talking about the screw that restricts the movement of the throttle arm on the control plate. The one that the throttle cable actuates. And it is fine, in my experience, to do this. I have a predator 212 with easily 40 hard hours on it, and I haven't had a problem with it.
I'm 99% sure that he's talking about this screw.

yup its that screw. Can I take it out to get more speed out of my go kart?
proper carbs use a screw, not a fixed stop..
nevermind...
even with the cotrol plate limiting screw
you have the exact same problem:
NO YOU WILL NOT GAIN ANY SPEED
(if that limiter screw is properly set, it is set at exactly the max rpm!)
you only put load on the stamp steel plate mechanism,
whcih can easily bent back if you exceed it's mechanical threshold though..
so removing it doesn't make any sense but wouldn't cause any real harm either.

Well it ramps up the rpm to a certain point I can tell cause mine was probably screwed in a bit. Some people put the rpm down with the screw because if they use it on work machine that doesn't need to go as fast they will screw it in so it isn't set anymore. Doesn't a honda have a built in govener?

Yes they do... an internal one connected to the outside of the motor via rods and springs......
Also some say there is a ignition coil that also has a transistorized eletronic limiter...
