I am in the proccess of cleaning the carbs, and the book (Clymers) says to remove the main nozzel. Well I cant get the screwdriver in the slot because the idle tube sticks too far down. Also, the book says that the tube should be bent so as to contact the side of the main nozzle, and it is not. They also have a note that if the tube is note touching it will cause the motor to run execsivly lean. Anybody out there know what the deal is??? Thanks a million Greg
