I put an OldMiniBikes Warehouse Stage-2 Kit with a Comet Torque Converter on a Coleman CT200U-EX. The kit comes with a Non-EPA carb and a .037 main jet.
It’s my understanding that the stock jetting is a .028 main and a .016 low speed. I did some searching and I don’t see a lot of info on carb tuning.
I was wondering if it would be smarter to go to something like a .020 low speed and try a .035 main. Adding fuel on the bottom should increase throttle response and taking a bit out on the top should should just balance the bigger low speed.
I also noticed that the exhaust pipe inlet shape was far from ideal so I reshaped it the best I could without compromising the weld.
