How in the heck did this topic go from me showing a half-way decently maintained lawn mower engine to crap about Garbage Caddy's? Cadillacs have gone downhill since the 1980's. All they are now are re-badged Chevy's and GMC's, with a power ashtray and phony walnut trim and made in Canada (not the United States).
My post was about proving Engine Design has a lot to do with sludge. The Geeks at B&S design these little engines for abuse. The tolerances are loose, the oil galleries are as big as the Lincoln Tunnel, and they are simple. These little engines are designed to see severe service, that no vehicle engine will ever see, unless you convert you caddy to a lawnmower.
I do buy American, Yes, my Titan has a Nissan badge on it, but it was built in Canton, MS. The engine was built in TN. I don't care for anything built by UAW, and their 10 minutes work, 20 minutes break, 45 an hour to bolt wheels on the lugs, then have 3 Union meetings to get more $$$ for doing a crummy job.
