This is really nice watching your journey back to your street bike. Looking forward to the video when you get to show off your bike back in great riding condition.
Get yourself a ultrasonic cleaner. It's a game changer for cleaning carbs. I use the green heavy duty degreaser concentrate in my cleaner and it works so good. I take everything apart and pull jets and in the ultrasonic it goes.
That one carb had considerable moisture in it. Fuel and air will not flow correctly. Get that cleaned up and put back together & you shouldn't have anymore problems. 😊
