Haha I understand! No, my painting days are over, I'm keeping them all original patina from here on out. Even with less-than-perfect paint condition I've found I really prefer original. That goes for engines too, however, the only aftermarket engine if throw on a deck would be a honda GXV140 or 160.
I would really like to find an old bricktop though, speaking of lawnboys. Yours is 21 years old, does it have a Tecumseh? Actually I'd like to find an old early '80s crappy craftsman like the one I had when I was a kid...but I digress. How bout some pics of your lawnboy??
