Not easily. The carb has YD cast into it. Idle adj. screw and mixture adj. screw (closest to air filter and capped off) and the letters C-32CNS66EPA on the fuel bowl. (I think the first letter is C...It's kinda smeared)
You should warm up the motor and then do a plug chop while riding in the region that you are experiencing bogg. Then let the motor cool down and pull the plug and examine it to try and determine what condition is causing the bogg...I got a new CNS carb with my bike kit. Capped off mixture screw, only one slot on needle for e-clip. Starts good, idles good, ok power on the low end , NO POWER at mid range to full throttle. (bogs down) I can take the cap off the mixture screw. Now what? Where should the float be adjusted?
I would look into determining what adjustment in the mixture need be made before worrying about how it can be done. The cap on the air mix screw can be popped off and the screw is there below, but the air mixture screw adjustment isn't going to cure a situation where it runs good at low RPM and boggs at mid to full throttle...How do you adjust the mixture with the screw capped off and only one notch on the needle?
If the vent is full of gas the float level is too high or debris is holding the needle off the seat under the float. I got my drill set from amazon for less than ten bucks shipped, it has a hand drill which looks like a ink pen. We are talking about a smaller jet, my stock jet was a #71 drill bit size. Fix the float problem first then the jet. Does the carb have the vent tube going to the back of the air cleaner? If so pull it out and try a test run.Don't know the jet size. My bits only go to # 60 and it's too big. We're talking about the bigger main jet...right? Also the bowl vent tube is always filled with gas. I have it in an up turned position so as not to spew gas all over my bike and leg. Is this normal? And.....why should I need a new jet on a brand new carb? Why wouldn't it have the correct jet to make it run right in the first place. Would this carb work at a higher elev.? I live at sea level
A little blowback from the carb is to be expected RE: mist.Ok ...I did the test. Ran worse with the choke on. Spark plug was wet and had oil on it. Ran better with the air cleaner off. When I rev the motor with air cleaner off, A little fuel mist(????) come out of the carb. I guess it sounds like it's running rich. What's the fix?
Like I and others have said, you need to adjust your float so it closes the needle valve when the float is lower in the bowl. The rich condition and the fuel in the overflow indicate that your float needs adjustment. Once the float is set to hold a lower fuel level in the bowl the overflow tube will be empty and the rich condition will lighten up. The main jet is the biggest of the 3 jets, yes....Don't know the jet size. My bits only go to # 60 and it's too big. We're talking about the bigger main jet...right?
