Need carb that fits manifold well

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

When you say. 66 is that of 1mm I take it?

yep

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.
