A 30mm carb being sold by JFG RACING on eBay is a total waste of cash !! It's a CVK carb that comes with a 118 main jet and I think it was a 43 pilot jet. The 118 main jet and jet tube are not made to fit the regular 150cc type cvk carbs . They are made for the smaller carbs that are made for the smaller 50cc carbs. This means they are unable to easily tune your scoot If u need a larger main jet. I haven't been able to find a jet larger then 118 that will fit the jet tube. It was so frustrating. I took the jet tube from a 26mm cvk I have and the jet tube did screw into the carb , however the tube is too short . I bought 2 of these carbs when I ordered them and it was such a headache. I finally decided to look for another 30mm carb and found the same type I had years ago on my first scoot. It was from gy6racingteam on eBay. I paid about double the price , but I'd rather pay $100 for a good carb that works . It was sold as an Oko cvk carb .

I have had a similar type of deal where i noticed thee jets being shorter aand very hard to get a good tune. is there a given length that I should be looking to use on a typical factory 150cc carb (not jet size itself as i know to play around that way). I've ordered a feww diff carbs and finally a set of jets but now i don't which was which from the originally good running carb after a couple yrs of this and that and i tend to just get by before trying again. even the pilot jet seems short.

The 30mm carbs I ordered for my 150cc scoot used jets in which I was not able to replace the main jet with any of the other jets I have. The thread size and the jet itself was smaller , to the point that u could not get any of the other jets to even screw in at all.ill have to take a look at the pilot that's in them. I forget if the size itself was smaller or not.
