HELP! How to open this carburetor cover??

Pull it apart like the other guy did and make sure you pull that oval shaped white plastic thing out of the bottom of the carb and spray that with carb cleaner, use the carb cleaner to really blast out the passages in the white oval and up inside where the white oval goes with the carb cleaner.
Mine was running bad so I gave it one glug of techron fuel system cleaner and that stoped it dead. It softened the varnished gas and turned it into gasoline bugers which plugged up the carb. Disassembly and a good blasting of carb cleaner got it going good as new.

I just watched a YT video where he suggests drilling out the cartridge tiny main jet to a larger size. Will give this a try.

What the plug look like?
Chances are it doesn't need more fuel

Plug is fairly new but will check again. This may take awhile to know if widening the jet (only 1 or two steps above) will make a difference. I now radically accept that carbs are plastic. It actually seems automotive intake quality plastic so perhaps it will last. The butterfly being plastic is the worst part.
