I have a lawnboy easy stride gold series 2 cycle version. Purchased around 2004 ish. Went to start it yesterday and when i pulled it acted like it was locked up then the motor popped up off the deck and fell over. Looked close at it and found that there are only two pillars that connect the motor to a collar that is attached to the deck and both pillars had cracked completely thru. So i know isn't repairable but would a new 4 cycle engine fit in its place? Nothing wrong with the deck and the drive system works great. Well it did before the motor fell off.
