Ok so I got it to where it is rideable but it is deffinatly not faster actually slower and the takeoff is almost the same. I am sure that I am missing something. Am I right by saying that the pilot jet is for Idle? I left the old pilot jet in there when I changed the carb. i am thinking that my main is to small. I would like to open up the case and see if there is a restrictor washer in there as even going down hill it doesnt wind out as it did before. Also I need to see if my cdi is limited.

I would stick a 90-95 main in there and work down. Way safer to start rich than lean with a 2T especially. Forget everything else for now, until you know that carb is right. When you start messing with multiple things at once, it just makes everything more difficult. This has good info on what all the systems in the carb do... hondanighthawks.net/carb14.htm |

Ok well just went for a ride to the store and it ran slow but ran. I am playing hookie from work so I cant get to my tools but tomorrow I am going to buy a plug socket and some plugs. Then it is plug chop time. I think i have a local source for jets so I am going to probably take the scooter there and try different jets until it is right. I am going to start with a 95.

www.ultrapowersports.com/The owner out there is a great guy. My father in law has bought many scooters from him and he is willing to help anyone out. He offers in house financing and if you go in and talk to him and you seem like a reliable person you can walk away with a scoot for $400 down. His prices are a little high on scooters but he does have to keep the doors open so that is expected. But I am sure he has jets there.

Ok so here is the verdict. It is running way to rich. It is choking on fuel. Literally it is flooding out. Why could my 100cc motor be choking on fuel when it has a 78 main and the screw 3 turns out. This is so frustrating.

I would suggest checking the float height to start with. If the float height is off it could flood the engine no matter how it's tuned at any throttle position.

aside from the float have you checked the whole filter/filterbox, an obstruction would cause a rich condition, unlikely but?

I checked it but here is the situation. The airbox that came with the motor was broken so I put my old airbox on. Then I put the filter from the new box in the old one and put that on. It is a little bit different but from what some people have told me they have had to drill holes in the box to get it to breath right. I put the new carb on with the new jets and it seems to have helped a little bit. i checked to make sure that the vacuum petcock thing isnt leaking. i still had more power with the old 50cc motor so I know that I am not there yet.

Ok so I am a little confused as of late. I have a screw on the intake side of my carb. If I screw it out that makes the mix leaner right? Because I just found 2 different sites saying otherwise.

It depends on the carb. If the screw is the engine side it's a fuel screw, in=leaner. If it's air filter side it's an air screw in=richer. |

That screw is more for the idle mixture. It there to smooth out the idle mainly but having it properly adjusted also helps the engine transition from idle to open throttle better. In no way, shape or form is that screw going to affect the main jet at wide open throttle. If you are waaaay too rich and/or bogging at WOT then it's either a problem of not enough air getting to the carb, too much air getting to the carb or like Brent suggested the float is set too high so the carb is too full of gas. You lower the float by bending the tab on the float upward a little bit so the float needle closes off the incoming fuel a little sooner thus lowering the fuel level in the bowl. Same as a toilet only upside down.
Are you noticing fuel flowing out of the carb/air box when the scooter isn't running? I.E. a Puddle of fuel on the ground

no puddle on the ground. What about the needle? I am going to try and drill some holes in the air box right now and see if that helps at all.
