Hello All: I have torn down the 25cc engine of my 12 year-old Blower all the way down to the lower end (crank case and crankshaft). I was wondering if anyone knows the proper (or any way) to remove the crankshaft from the crank case. I would like to accomplish this task so I can thoroughly clean everything properly. Thank you in advance for you assistance. I have provided a picture of the crank case and crank shaft.
