Warning to all 66cc/80cc these are M4 thread. If you have a makuni, pwk, oko or any of the clones these are not the ones for any of those style carbs. Those all take a M5 threaded jet. I just learned the hard way and didn't fully read where it said they were m4. Having to send back. For those of you that need these they are very easily readable, and look really in excellent condition. It sucks they're the wrong thread cause is sure like to gotten my bike going

Decent assortment of main jets for a stock 139qmb/1p39qmb carburetor. Labeled correctly as far as I can tell and there is definitely a difference in performance if you mis read and install the wrong one. But that's mostly my fault. They work as advertised

Fit my GY6 QMB139 49cc carburetor perfectly. All jets are marked/stamped really well and are easy to read. Good sizing/gaps to really dial things in!

Half of these were not labeled as to what size they were. The ones that were labeled weren’t not the sizes stated in the description.

They are small so the numbers are as well but fit the factory carb on my taotao hellcat and worked great
