Any one know of any carburetors that work at high altitude for a 66cc motor? I'm a large guy who wants more go out of his set up, but am new. I have been told that a carburetor is a good upgrade both for power and responsiveness but wont work at my altitude of 7,083′.

No, it's simply too much altitude for a china girl, after you rejet the carb you're going to need a high altitude air filter and HA muffler clamping system, the lower air density causes the muffler to expand and crack so due to new stresses you'll need the advanced muffler clamping system from gasbike.wok

High altitude tires (aka mountain biking tires) are useful too.

the carb doesnt change for altitude. you just use smaller jets. less air=less fuel.

wack a good tuned pipe on there, a REAL one, not just some cheap chinese bling, and the increased boost they give will make up for the reduced volumetric efficiency...

ideally, you use a walbro carb so you only have to tweak a needle when you come down below the snow line...

7000'...wha, about 2.2km or so? pffft. thats not that high... even if it IS higher than anything in australia...
