Review on NIBBI Racing Performance Motorcycle Carburetor PE28mm 150CC Carburetor: Jets for Honda Yamaha Suzuki Kawasaki Scooter ATV Dirt Bike 150CC-250CC CG GY6 Engine by Shane Yay

Carburettor looks great but has terrible problems. Not sure if the quality is terrible or gone. The 26mm Nibbi I bought for my son's bike worked great right out of the box. That's a ton of questions. I've tried so many pilot jets and still can't get them to idle well, not great. I would appreciate a good idle. The mixing auger can only be unscrewed half a turn or more, the idle speed is very high. Upgrade to a taller jet plane? Definitely there is. Stick 40 in and the turnover was super high. even to screw with the mixture to the stop. Increased to 48 and everything is ok. Tried 50 and it was smoking due to the amount of fuel. Went back to 48 and the mixture screw is still only a half turn out. Even 3/4 and that is ultra high speed. I can turn the idle screw all the way, it almost doesn't fall out, it doesn't slow down. Sometimes he will shoot, and sometimes he will want to die. I went back to the stocker and I think it will make a good paperweight.
