My Italian 150's all run with a 26mm carb if IRC my Znen 150 came stock with one. If no mods that would be fine.

I run a 28mm oko pwk. Mine is a 170, but I ran it when it was a 150 too. 26 should be fine.

I got a 26mm cv carb from partsforscooters with some jets. Instantly put a 130 main jet and strapped it to a brand new 150cc with no tuning other than idle I have already stuck 200 miles on it with it running very well. I do have a open exhaust and a foam filter.

I ask because with the same setup, 26mm & UNI filter with open exhaust I was at 115 main. 130 would be flooding it and if it runs it would actually be robbing you of power. Might even be prone to cylinder washing... |

I'm in va and this new motor is getting broke in wot. Dex. You hooked me up with the parts. I do know this 150 runs way way stronger than the 50cc and I know I need some tuning and I do have the stock main that came with the carb I got from partsforscooters also have a 120 and a 130 main in stock but I put in the 125 before I even started it go first time and it runs very very well so if I can tune it better then Damn it will be fun ...... |

Well hey if it works, run it! Just sometimes when that big of a jet is working, it's cause of a small air leak somewhere and you are just creating a better mixture with the larger jet. Might wanna double check everything just to be sure.
