New Guy with issues

Folks,

I just retired after spending the last ~30 years working for the Army, with the last 14 in Europe, which means my Sensation (bought second hand for jobs doing lawn work during HS) has spent the last 15 years in storage stateside with only the body handle and wheels - no engine (don't quite recall why...

So the question is: what are my best options for getting a motor, blade and catcher on this orange beast to terrorize small animals, torture my Son and future grandchildren?

Cheers,
Sean
