    So I received an offset intake manifold yesterday...and it seems to be a bit too large for my NT carb. I had to loosen the flanges with the stock manifold and upon trying to get it on my flanges broke :(. Woops.

    Anyways, I'm in the market for a carb and I want to make sure I get one that will fit and form a proper seal. The carb worked well once tuned before but I used a rubber elbow which would come loose with the way the carb clamps on. That's why I purchased the offset manifold. I have attached some images as well. Thanks!

    I have been looking at those! Do they perform well for you? And do you feel it is capable of a better seal and fitting on a pipe that seems to be slightly larger than stock?

    ^^^ I know that's hard to give an answer to.. just more asking for your opinion.

    Thanks!

    I found thay go better all round bit more nippy maybe some top speed gain but you need to get jets with them or your stuck for tuning.my one for 66cc did not. It would fly up to 40 kmh and then bad dirty note and sit there. That next carby up with all the tuning you can play with and handlebar choke is worse. If you got the money go for it but thay don't work out the box unless your lucky

    Thanks for the advice. Ended up picking one up in a kit that included 5 different jets and a throttle cable. I also ordered another offset intake manifold that is a bit longer just in case. Hopefully everything will work out with one of them :D

    I got this dellorto style carb off ebay with the air filter for about 20 bucks. I used the stock NT carb metal cable inlet piece and put it in this one so I could use my stock throttle cable. I have jetted it to a .66 and it runs way better than the NT carb that came with my engine kit. Check out eBay just filter for US sellers if you don't wanna wait 2-3 weeks for shipping from China lol.

    Have hade good top speed with this carby but I have got the same with the stock one. But no doubt the motor run heaps different. My stock one poo pop when I let off the gas the clone or hp revs down like a motorbike sounds nice wrammmmmm

    Very nice. I picked up this kit here, so hopefully one of those jets will agree with my engine/elevation. And yeah, I don't like waiting for China :p

    I think that's the same outfit I got mine from over eBay though. I'd start with the .65 jet if the stock jet doesn't perform well where you're at.

    I agree the Delortto clone is the best. I have tried 6 differant carbs the NT being the worst and the clone being the best. .66 jet is a good average. The carb will not work well with the original one that comes in it. Also before rejetting you must remove the air filter and replace it with a piece of nylon panty hose. The original filter does not let the carb breath well enough for the 66 cc China Girl. If you get a high compression head with large fins to produce torque and lower heat, you will see a huge differance. And if you install an expansion chamber type exhaust, you can really take advantage of the added torque and increase your top end. If you add a ported cylinder, well then you have a really good package. Low end torque, midrange power, and 45 mph all day with no overheating problems. The best part about all of this is that you can have a lot of fun, dramatically increase the engine out put and spend under $200.00 bucks. :p
