    Does anyone have one for sale or could someone tell me where I can buy the Carb? I have looked at about 10 different suppliers and they all seem to carry the CNS, which I am hoping to stay away from. Any help would be greatly appreciated. Thanks, Walter.

    I have one for sale

    In fairly good condition, however missing primer button. I filled in the hole with a tight fitting screw and it works good. I have found however that the NT carb i replaced it with is much better on my 66cc skyhawk. Float sometimes sticks on the speed carb. No amount of adjusting improved that. I have had the NT on there for 2 months and have had no leaks. It also has a nicer air cleaner assy. Only drawback i found is the throat is smaller, but the NT ran so much better, I actually have more power with it. I found mine at ebay for $15 bucks. Including shipping, but took 2 weeks to get here from china. The guy or gal has an ebay store called sun-thing28. Currently has one for the same price, the item#is 140586768715

    those dellorto's are awful pricey the 15.15 is $68. They sure do look a lot better built if you got the money. i'll have to stick with the nt cause i'm financially challenged!:8:

    Ditto on the $$. My current carb is leaking like a sieve. I've got a friend with a month old nt he's gonna give me for $10. I'll probably still upgrade to the 66cc NT when I have a little more cash reserve.

    To my knowledge the nt is the same on the 66 as the 49cc. I could be wrong though, I never owned any that came with a kit. $10's a good deal. If it doesn't run right sbp has the jets. The are the same for nt and speed but not for cns. I got a .66mm on my 66cc skyhawk slanthead but it is still a little too rich. Pretty sure .64mm gonna be perfect.
    Which carb do you have thats leaking?

    Stock NT is the culprit.
    My understanding is the throat is a "Little" bigger in the 66cc. Something like 3mm iirc.

    the speed carb is 3mm bigger than the nt. I got both, But if im already running .66 jet i don't want any more gas anyway

    Will do. I did some sealant work on my gas cap to hopefully fix a leak so it's setting overnight. I'll be out when daylight comes though to see if I have a running machine or not, lol. It's a CNS, I had wanted to stay away from them but for $10 you can't go wrong...

    Maiden voyage with the CNS-V2 carb. First off I had to remove my ported billet intake, not enough clearance and the **** carb chewed up my o-ring. So crappy stock manifold installed. Went on a 20 mile (each way) trip to see my daughter. Ran great, plenty of take off power, does get a little choppy from 12-16mph, Wants to run around 25 (Tucson limit is 20:annoyed: ) Engine idled nicely. I have to go into the foothills to get to her house, so I got to really see what the carb would do. It ran OK on the hills. Going from a stock NT to the "super" V2 I would have expected better, but it did haul my :poop: up the hills & I lost the ported intake. It has a fuel leak that I haven't been able to track down, albeit a small one, just hate seeing that drop every 10 min. If I shut off the fuel valve it seems to stop. I'm open to any suggestions about tracking down and fixing the gas leak. :detective: Also checked the plug, little oil build up on plug under the washer, but electrode is nice and med tan.

    gas leak

    Hi there I am having problems with mine leaking gas from the float bowl drain screw. I replaced the red fiber washer with a plastic one. It worked for several days but is leaking again. I took it off and apparently i tightened it too much. The bolt cut into the waher a little. I tried flipping it over but it still leaks. I have tried white teflon tape in the past. It doesn't hold up well with gas. I read on the google they make some that supposed to work with natural gas that is yellow. I'm gonna try to pick some up today, I will let you know how it works.
