Lawn Boy 5253

I've had this mower for several years and it has never run really well. It now is to a point where it is not usable. It runs pretty good when first started but after a few minutes RPM's drop way down and it smokes really bad. Float, needle and seat have been replaced. Muffler has been checked and it is not plugged. Am I looking at a bad crank seal? If so how big of a job and are parts available?

Thanks
Ray M
