The go cart guys will use different emulsion tubes and main jets. Not to mention intakes and exhausts. I dont see them messing with the low speed jet. I am not an expert or someone who frequents those board much. But when I do, I do not see any talk about the low speed jet. I know you can buy larger low speed fixed jets. So maybe some people do. But it seems far from the focus. Maybe becuse they run them as fast as they can go and are not too interested in the idle speed. Most people only run their snow blowers on high and only throtthle down when they pause to do something else.
I have purchased after market carbs and had to mess with them to get them to work right because they are not exact replicas of what it is replacing. To say it is simple ignores murphy's law. You neet to have some understanding of physics and how carbs work for you start changing things. Sometimes it is simple and sometimes it is not simple.
If you have a new Honda and you have stock jet that is surging. It should be simple to try a few larger jets and optimize the mixture or get it close enough. Preverably get an adjust able jet and be done. I agree, you dont have to understand alot if all you need to do is what is in that instructional video above. You can just change parts and gauge it by the sound of the engine.and done.
