You must be a NASA engineer to disarm the carb and then pretend that works! I take some photos when I change the oil. Maybe can help someone else. Here there is the top part of the carb.
oil is right height when halfway up sight glass.is your filter stainless or paper. new motors now have a paper filter. often on first oil change you find steel in strainer.
There are 3... Two on the right hand side, one has two m6 bolts holding it in, and to the left of that is about a 17 or 19mm plug with a thin long washable screen with an O ring holding it into the plug. Same thing on the gear lever side of the engine. Both are the same plug/screen
