I got one of those lawnstation engines also and I found both Crank bearings were just about seized. Wish I'd looked at it right when I received the motor! Anyway the local saw shop ordered the brgs. Only took a few days, cost about $23.00 a set. These were the one piece bearing and seal type. BTW besides the bearings the carb was also bad on this puppy.[:'(] I might go for another reconditioned saw, but not just a powerhead like I did this time.
