The story so far, I have fitted a jetex 22mm carb to my TV200. It is a carb I have used but only sparingly in the past and is vitually brand new, it was sat in the garage and so I thought I would get on and fit it. Having fitted it I took the scoot for a short spin of a couple of miles and it ran really nicely, nice and responsive and pulled well up hills. I then parked the scoot in the garage for a couple of hours and when I went back to kick it over it started fine but when the revs are increased it immediately started coughing and spluttering and then finally stalled. So I took the carb off again and double checked all the jets/floats etc were clean and operating well and no problems everything was ok. So I refitted the carb but I still have the same problem. I would be interested in any ideas of what is going wrong because it is completely baffling me. Thanks

It could be coincidental that you fitted the Jetex it could be an ignition fault I suppose .

Jetex carbs are great carbs providing you do all the finishing that the manufacturers neglected to do.
I would guess that it is either the atomiser air jets blocked the pilot jet blocked or the float or float needle sticking or the tank isn't venting through the cap and you have a vacuum in the tank.
have you tried running with the filla cap off ?

The floats are notorious for sticking. Remove the float and rub the edges where the pin goes through on some fine Emery paper to give the float some side to side movement when it's fitted. You may have to enlarge the hole in the float for the pin, as these can sometimes make the pin a tight fit in the float preventing it from swivelling correctly. All learnt from experience !
