And in those cooler temps (4c) you should be at least 1 size richer on jetting , as the temp warms , then be where your at (at 16c)
When you installed the new Fuel Screw , are you positive you got out the old O-Ring and washer ??, this could create a lean condition
The easiest way to check the fuel level is to drain the carb bowl , re-tighten the drain screw or bottom nut , pull the carb and undo the float bowl , then set the bowl in place but with no screws holding it , then connect the fuel line with the carb next to the engine (outside the frame) , then hold the carb level by cupping the bowl and turn on the fuel , wait about 20-30 seconds , then shut off the fuel valve , while still holding the carb level ,hold the carb itself with one hand , and with the other lower the bowl , and see where the level is , it should be about 3/4 full
You can do this with the carb in place , as well , but its kind of tight , you need to twist the carb enough so you can get the bowl screws out , then put it back level and do as mentioned above
