Review on 🛵 High-Performance GOOFIT PD24J Carburetor for GY6 150cc ATV Scooter with 157QMJ Engine by Chuck Derrick

This was the correct replacement for the carburetor on a 150cc GY6 engine on a Coolster 3150DX-2 ATV. The engine started immediately after replacing the old carburetor. But it doesn't start after a month. I adjusted the idle fuel screw 1 turn and it worked fine for 6 months then same problem until the adjustment worked. I found that the pilot jet was clogged with low quality "tube brass" oxides. not designed to run on gasoline. My claim is based on green oxides all over the idle (and main) jet. The pictures show a defective nozzle (on the wire) and a two year old Honda nozzle. Of course, I use the same premium ethanol-free gasoline that I use for other engines (carbureted and fuel-injected) that don't have this problem. I cleaned the nozzle by widening the inside diameter with .008" wire and slowly working it up to .018" with progressively larger wire (six side holes were also blocked). If you check the forums, this is incredibly common on GY6 carbs. It's like these GY6 carburetors have thousands of bad jets made of incompatible materials. This isn't just a Goofit problem! Note: I originally wrote that the automatic choke fails because it is temperature dependent to "appear" between shots. It was NOT an automatic choke.
