i had success with the chinese carb
this was 10+ years ago a low top early bbd with the accelerator pump rod through the top of the bowl sold by "sherryberg" on ebay/aliexpress
mine came to me as a 318 carb and i neded one for an austrlain 265
so i swapped the rods jets pump jet weights ball bearings and spring from an old worn 265 carb into the chinese carb and it ran ok..
i used my orginal base gasket
my original pipe for the choke vacuum kicker
the main benefit of these carbs is getting a carb base that is not completely worn out at the throttle shaft bushes
and a top with intage horn that isn't buckled due to too tight on the air filter clamp
the whole top of your old carb grafted onto the base on the new carb might be just what you need.
one presumes if one factory in china had success making these things for somone a whole load of copy cats now exist... they used to come out of the factory that US companies like EMPI and Entek used for Solex/Kardron 40mm and Weber IDF and ICT copies.
JinLin Fajs was the company in china they make decent throttle bodies.
the quality of mine was not great, the hardware is none standard the pipes and gaskets were crap but mechanically it wasn't bad
i.e if you had to buy a chinese carb get one from Jinlin Fajs they at least potentially made them at the request of some US company, so at some point had strict instruction regarding specification and quality.
thir name will also appear on the Carb or its packaging...i.e indicates some pride in what they made
