I have tried two pairs of Empi Hpmx 44mm carbs. They were absolute junk. One pair had porous float chambers that leaked fuel behind the Venturi and slowly flooded the engine. That was a problem that took an age to work out what was actually going on!
The other pair just wouldn't tune up, no matter what I tried. In retrospect I imagine there was a similar problem as above.
After wasting a day's worth of labour, I vowed never to buy Chinese carbs again.
