I recently purchased a new carb because old one was just somewhat falling apart and i figured with all of my other upgrades the 20mm opening would help with performance. i have been riding it around a lot lately with really no problems but upon installing the new car. with the same jets i had in the other. it will not start. sounds like it wants to but will never actually turn over.

Sometimes it take a minute or to to fill the float bowl and get some fuel to it but have made sure everything is sealed good screwed tight on both sides of the carb and both the fuel and vacuum line are connect right, also might want to make sure the drain screw is screw tight also

ok well it actually did fire up at first then slowly died. will not restart. The drain screw is tight. side question.. my old carb had a post for i think overflow on the bottom which is not there on this carb. it is where the drain screw on this one is. and there was a hose attached to the carb next to that screw where there was nothing on my old carb.

Do you know where the FUEL RATIO SCREW is? If so turn it clockwise until it stops, do not force it tight just until it stops. Then turn it out 2 1/2 turns and try to start it. Many times the carbs come with the Fuel Ratio Mixture either to OPEN OR TO CLOSED. 2 1/2 turns out should is a good starting point. The carbs will come with a DRAIN HOSE at the bottom of the carb to drain the carb bowl. Two types of carbs, Both Normally will come with a hose attached to a connector at the bottom SIDE of the carb. The difference is one carb may have the DRAIN SCREW on the end of the HOSE fitted on the end with a piece that the drain screw screws into also that type will ususally have a wire wraped around the hose. The other type has just a hose and the Drain Screw is right next to the Carb built in. Alleyoop Let us know if it acts better after closeing the fuel ratio screw and opening it up COUNTER CLOCKWISE 2 1/2 turns. Alleyoop  |

thank you, My old carb was one with a drain hose with the screw at the end of the hose mounted near the CVT case. does this mean i can completely remove this hose now? and secondly I have been playing with the screw and i did manage to get it started. only problem is now, after all of this work i have worn out my kick start and now it either wont catch or it grinds and stops. my electric start has never really worked

First off, let's get that electric start working. The kick-starter is mainly there for a dead battery start once in a great while, not to be a daily user thing. They're like everything else on these chinese scoots and that's usually flimsy at best. OK, maybe that's being a bit harsh but hey, it is frustrating. As for the carb issue, well... what I would do is be sure the new carb is clean and clear of any dirt. You did mention you're using the jets out of your old 1...why? IMHO Unless they're an upjet and the carb is identical I would go with the ones that came with the new carb.

The new carb should have come with a hose to put on the carb drain connector if NOT then take the old hose that was on the OLD carb and stick it on the new carb and you can take the screw on the end of it out if you want.
Don't know why you messed with the needle but put the clip in the center slot, that is usually how they come with the clip in the center slot. It is getting to much fuel in the mid-range with the needle raised.
And yes the next fix is getting your electric start to work otherwise you are going to break the kickstarter then you will be in a pickle.

Ok sooo, I have not touched the needle at all? anyways i am really not sure how to get the electric start working, (see my electric start thread) and also, I used the old main jet because its a  and i'm running a BBK and exhaust and uni filter so i need the extra jet. I left the idle jet in there however. |

Sorry I must of been reading another thread saying he raised the needle. I help a lot of people on different forums and get the folks mixed up.  Anyway do you remember how many turns out or in the Fuel Ratio Screw is currently at that it started for you? Need to know to determine if to much fuel or not enough with the PILOT JET that is in there. You want the motor setup so it starts on the 1st or 2nd kick or 1st or 2nd push of the elcetric start none of this cranking and cranking stuff which means something is not set right. So with that said, EXPLAIN what the ELECETRIC start does or does not do. Here are a couple of questions right off the bat needed answered: 1. When you turn the KEY ON AND SQUEEZE the brake Do your brake lights come on? 2. If the Brake Lights come and you push the START button does it spin your starter or do you hear CLICKING. 3. IS your battery good. Alleyoop |

Mine would't start either with the new carb (but did turn over). I just took a straw, dropped it in the gas tank, put my finger over the tip to create suction, and dropped a straw full of fuel into the carb through the top; problem solved.

He already had it started once with the new carb, you are thinking the carb needs primeing which his has already gone through that.

ok so i have the a/f screw about 2 1/2 turns out which is what i have always read was where i should start it out as. It did start and i rode it around the block and tuned the idle. its hard to tell if it starts better on idle or with some throttle because its so damn hard to start because i cant get a good crank on the kickstart. as for the electric start. the breaklight comes on and when i push the electric start button (which i might add is not stock) it will give a very faint reving souund (electric sound) but after a couple tries it clicks. The battery is good as far as i know, I charged it up before install and it is much bigger than what was in there. Fuse is fine. the settup of electric start is not stock im fairly sure. Which i tried to explian in my other thread

Sorry alleyoop for the confusion it's my thread with the needle raising. As for the electric starter I'd check continuity of the switch and see to it the starter motor is catching the starter gear, If not you'll need to replace it.

Which i tried to explian in my other thread Take a picture of the start button or whatever is on there. If you hear a whirring then it is spinning the starter but the bendix may not be coming out to engage the Variator Fan teeth. So you will have to take the CVT cover off and check it out. But if do not know what you are looking at TAKE Pictures of the CVT with the COVER off and we can point out what you need to check out. Alleyoop |
