[90] Quad 110 Chinese Carburetor Adjustment Guide - Tips & Troubleshooting for Low Speed Issue

Hello people, I have no more strength with this carburetor, I still have some halo and if I want to see how to adjust it, something is different on each forum, or I don't write what to do with the screw to turn and sneeze or buy a new one and buy a new one and what's going on at low speed I no longer have the strength of quad 110 Chinese thoroughbred as if someone could write what exactly I should do, I would be very grateful. Briefly Please help with adjusting the carburetor.

By screwing this screw on the revs you raise the needles and hence the revs increase because the engine gets more air and fuel. You also have a second screw that adjusts the composition of the mixture, try to screw it all the way in and then unscrew it with one turn and adjust the speed. If you still can't adjust the RPM then make sure that the problem is not somewhere else, e.g. timing, valve clearance, leakage, exhaust problem.

Oki will try but not today thanks for help

Also check the color of the candle after cutting, if it is black and smoky, it means that the engine gets too much fuel, it should be light coffee, of course the air filter must be clean. Adjustment can also be made by adjusting the needle height, there are probably 5 grooves for setting the fuel dose.
