Descent carb for the money. The phillips head screws suck because they were way to tight and could easily strip if you aren't careful. No junk or metal flakes inside no casting flaws.
Recently was able to apply it to my 50 CC bicycle engine kit. Even when untuned It does a lot better than the stock Chinese carbs that exist. I haven't fully tuned this yet so I have yet to give a full review. My only dislike is the hardware was torqued on way too tightly on the bowl end to where both screws stripped out badly. Other than that its better than what I had especially for the price
The first 21mm oko it run rich on idle circuit no matter what size idle jet so sent it back bicycle -engines sent another out,i did get it to run fairly good but i had to tune and tune no matter what size main jet or what position the needle was at it still bogged mainly on the needle circuit so what i did was put the needle in my dremel and used fine sandpaper to take 1.5thous off the needle tip,now the carb performs ok.im not saying every one of these carbs have the problems i did but if one would get one as described you better have experience tuning carbs or want to learn how.bicycle-engines does back there parts up so that does help if you would get a problem part.
great lil carb for my setup.. can be easily tuned and looks amazing
