After asking about my QT50 having no power and blowing some white smoke yesterday, someone suggested a crank seal. After work today I took the top end off and the cylinder jug walls feel perfectly smooth and besides some carbon build up on the top of the piston it looks great.
While I had it running I decided to just change out the transmission oil. Turned her off. Opened her up and the oil was a tad frothy and full of super small air bubbles. I'm assuming that the right side crank seal needs to be replaced at this point.
Has anyone ever done one of these? If so. How easy is it to do?
