So, I took apart the carbs today, and found a fracture on the main nozzle about 1/4 inch long(according to the manual, there's a pilot jet, main jet, and main nozzle) and the thinkness of the hair. The same carb that has this main nozzle is the one that constantly runs rich no matter what adjustment I do do it.
So, my questions are:
1 What exactly is the purpose of the main nozzle? I did some reading and know what the jets are for, but not sure about the main nozzle
2 would this fracture be the cause of the richness?
here's some pictures for it
any help will be greatly appriciated
