I am in the middle of this right now and let me tell you it is a mess!! Take your time and be REAL clean during this effort.

I added a zoomed in picture of my PTO carb filter. Now I know why my machine was bogging.........

ok sweet, thanks for the pic. i thought i was looking for something a little larger but once i saw what it looked like in your pic i found it right away. that thing looks really plugged, i had one that was jsut fine and one that was half plugged, im not sure how sensitive the machine is or if half a clogged filter would cause my machine to run as poorly as it did but i feel better with all new fuel lines for sure.

i was lookin at those oil injectors when i had the carbs off, do those things open from spring pressure or just an open orifice, should i clean those while i can access them??

Not sure about the oil nozzles/injectors and how they work. Good question and something worth looking into while the machine is apart. Do a search and see what you can find.
