Have anyone tried putting a 125cc carb on a 50cc based gy6 engine I run a gy6 125/150cc 24mm cvk carb on my 88cc 52mm gy6. The low end jetting is kinda touchy and stretching the vaccum slide spring a little is a good idea. Jetting depends a lot on engine size but 105 main jet works to get you up and going but fine tuning may be needed, pilot jet you're going to have to play with and see what works for you. Top end power and throttle responce are fantastic tho. |

Yeah I've been running a stock 24mm GY6 carb with a 108 main jet for a while; you need to use the GY6 intake as the carb won't fit a QMB139 intake. I felt better grunt and overall power when I finally did the swap. Also, the cable stop on the carb will need to be flipped over and held by one of the two screws, but don't worry, it won't slip if you tighten it down enough.
I swapped to a Mikuni VM22 PWK carb and it actually needs a 110 jet (breathes a little better); so I can't get any detailed pics for you right now.
