I have a new scoot. Bought it off a guy cheap because it wouldnt idle. I bought i new carb and put it on ran great. For some reason everytime i fill it up i cant get it to start its like it gets flooded out. and i saw some gas comming out of the evap canister(i think thats what it is) can anyone help. And ive also got problems starting it at times. but once i get it started it will run fine and idle fine but sometimes it dies but can start it right back up and it runs great. Ive installed a 130 jet and an after market air filter straight on the carb. also have a performance cdi, and a new NGK plug and new performance coil. I can get up to top speed but sometimes feels like a wheel bearing is dragging but its not. i can let off the throttle and it will ride smooth. I need some help. I am a vehicle mechanic. and this scoot is new to me and driving me nuts. and it really ticks me off when i go to fill it up and have to call the wife to come get me cause it wont start. but i can let it sit overnight and it will start and run just fine. cna i eliminate the evap stuff??? any help would be awesome. I love this scoot but its really getting on my nerves.

I love this scoot but its really getting on my nerves. TaoTao scoots have crap emissions components. Id guess your overfilling the tank and liquid gas is leaking down through the tank vent into your intake manifold flooding it out. Remove the PAIR system vac line and cap off the manifold nipple right before your next fill up and see if it helps. If it does remove that PAIR junk and ride on. |

Alright. Yah i thought that could be it too. But ive also only filled it up halfway and it still does it sometimes. but i will try that, and see what happens. so is there only one vac line that is in the pair system. and i think ive seen a video on removing the pair but it was on a 50cc is it the same on a 150cc? and thanks for the help so far!

I love this scoot but its really getting on my nerves. IMO, That jet is way too big. If you have a "free flow" (UNI, K&N) air filter, I recommend a 108, 110 max.... -------------------- I have a quantum Tour, emission removal is easy but one thing I want to point out, the reason your getting fuel in your emissions is because you're dumping too much fuel into your intake, it's being sucked into your Vacuum lines and going through your combustion chamber with some not being burnt/used and escaping the only route it has available... I will wager if you remove your emissions, you will see fuel start spitting out of your exhaust... Which, btw, do you already have unspent fuel coming out of your exhaust? |

Yes i have a knock off uni filter. And thank you for letting me know. ill throw in the 110 and see how she does. maybe that will help with the cutting out feeling when im at top speed. Thanks! and no i dont think ive seen fuel out the exhaust. have not really paid attention to it.

I put the 110 jet and its running pretty good now, but i feel like i had more power with a 125 jet and the stock airbox, could this be true? I know it doesnt sound right. Unless something else is broken that effects the performance. Im thinking about putting the stock air box back on and see what that does. But on another note. What are the stock weights on the scoot and if you upgraded what did you go to?

What are the stock weights on the scoot and if you upgraded what did you go to? If you have removed the stock air filter, am I correct in assuming you have removed your entire air assembly? Have you removed the ducting that goes to the air box? Reason I ask is because you have vacuum lines that attach to that duct, those line run off to to the emissions system... Well, if the air duct was removed, was the line that was removed capped off at emission connection point? I would really need to see what all has been done to this scooter to properly diagnose it. Also, if your scooter has had more fuel dumped into the cylinder than is being burned, it will quickly foul a plug, even a new plug. This will hinder performance. If it's a brand new, you may be able to clean it. However, a new plug is only a couple of bucks and it may be worth it to just get a new one. About the weights, I dunno. Haven't messed with them.... However, most Chinese 150's I've wrenched on have had 14 gram. You shouldn't ask other people what weights you should use. This comes down to rider weight and what type of performance results you're looking for. Take-off, top end, middle band? A combo of bottom and top? I advise researching this yourself. You will have much better results if you know what you're doing. Also, I advise against messing with the weights until you get the scoots fuel issues resolved. MY recommendation is this. Start from scratch (but keep using the new carb). Hook the stock Air-Assembly up and make sure the carb has a #35 and I would go with a 105~108.... See how it performs. If performance is good, start tweaking from there in small increments doing one upgrade at a time. |

Yes i removed the entire airbox and the tube, the filter is on the carb, and all i took off the intake tube was crankcase vent. And tied it up to the frame. Not anything vac on my intake tube. And yah i just want to get her running good. And alright ill mess with her a little more see what i can find. Thanks for all the help. This really help. And im looking for the best take off. Dont really care about top end. Because i dont hardly go over 50mph.

I have seen the ignition coil cause this problem. That would be my next suspect, if you have a spare try it . If you do not have a spare get one and try it.

dump some fuel in the vac line and try to start it. sometimes that will get the fuel system primed and pulling vac to keep it going.
