idk ct200u wont start after mods

Did you buy the bike new? Do you have the manuel that would have come with it? If you're running a header type exhaust and free flow air filter, the carburetor needs the .037" jet. There are 3 things that you could have messed up when changing the carburetor and or jet. One is the emulsion tube that sits above the jet when you remove the fuel bowl. Easy to get it in backwards. Also the gaskets for the carb. Easy to get them upside down. And also the plastic gizmo that sits between the carb and the head. I mentioned this very early on in this thread. I have a few brand new carbs that I could look at and take a picture of what I am talking about. Maybe tomorrow. So answer me the first two questions. In English.
I have Grandkids older than you, so if you want my help, don't call me bro. Got it.These things aren't all that difficult. I will try to help you. You don't need the carb that came in the kit. It's really no different than the stock one that was on your engine originally. So lets work with that one, because you said it ran before with that one on it. FWIW, I have 2 or 3 heavily modified engines, with the stock carb and the .037" jet, and they run very strong.

ok thanks but one problem the stock one the jet cant be removed

Why not. That sounds pretty strange. And you didn't answer the 3 questions I asked you. Bought new, owners manuel, header pipe and air filter. Also post some pictures of the carb that came in the kit. So I know what we are working with. 6 pictures. Top, bottom, and front and back, and of each side. I am not going to go into this blind. I have to know what you have in your hands.

I think you know what he has in his hand, hence forth no pictures. I can’t believe in this day and age he doesn’t have a friend with a camera phone.

Mr. Casey, for someone who wanted help, you sure don't seem to be very engaged or cooraptive. I said I would help you, so here goes. If it seems too basic or elementary, remember, I don't know how much you know or don't know. I only know that you don't know enough.
Pic #1 emulsion tube. Skinny end and fat end. ( screwdriver ) skinny in first. So the jet sits against the fat end. D shaped gasket. First thing that goes into the head.
pic #2 plastic insulator. One side is flat. The other side has a channel cut into it. The flat side goes to the engine, up against the D shaped gasket. The long think part goes down.
Pic #3 gasket that goes against the channel side of the insulater. Note the small hole in the upper part. The gasket goes on exactly as orientated. When you turn put the carb on the small hole in the gasket WILL NOT be on the same as the small hole on the back side of the carb, which are shown in Pic # 4. They will be on opposite sides.
Pic #5 gasket sitting on back side of carb. Hole in gasket is NOT over hole in back of carb.
Pic #6 outside or front of carb. You may have a paper gasket ( as shown ) or you may have a thin metal plate with rubber around the edges. Doesn't matter. Put on whatever you have and then install the filter adapter that came in the kit.
Pic #7 orientation of fuel bowl should be to allow easy access to drain plug.
The engine will not run without the plastic insulator. It MUST be installed as described. Same is true for the gasket in Pic #3. Had to be put on correctly, or the engine won't run.

We can postpone this whole ordeal until summer vacation. Hope you don’t have to get a summer job!
And the girls! Oh my, steer clear of the girls. Girls are better than minibikes.

 

[panchothedog]

Hope that this illustration helps you get your bike running again.

 

[Denny]

Girls are more fun to ride than mini-bikes. Only problem is getting the opportunity to ride one.

Huh?

 

[Edwin Spangler]

LOL

 

[Denny]

Girls!! Girls!! Girls!! Are more fun to ride than mini-bikes!!!!!!! Stupid auto correct.

 

[ezcome-ezgo]

I'm just a red-blooded boy
And I can't stop thinking about
Girls!! Girls!! Girls!!

 

[Sparkwizard]

Maybe there's a girl or two in the area who works on small engines! Maybe one of them even has a phone with a camera! Win, Win!

There needs to be more chickanics.

ok thanks but one problem the stock one the jet cant be removed

Could be stuck in the carb. Even the slightest bit of dissimilar corrosion or oxidation between brass and aluminum can "weld" the thing in place. Brass gets "verdigris" and Aluminum gets that chalky degradation. Combine that with an ill-fitting, wrong size screwdriver and voila.

The whole bike may be fairly new, how new I don't know, but it does not take too long. The process is quickened with that dang ol' ethanol blended gasoline....

 

[Sparkwizard]

Sometimes, the correct screwdriver makes all the difference. Also, removing a jet while standing on your head, trying to look up into the carb is impossible. In that case, remove the carb or invert the engine so your head it not the inverted part.

 

[Whitetrashrocker]

You just have to hold your tongue right
