Since this is a metal working group, I have a problem I need help with.
I decided to put a new muffler on my 8 hp B&S aluminum block engine,
the old muffler will absolutely not come out. I have taken the engine
down to the basement as it needed some repainting anyway and have been
soaking the muffler joint with PB Blaster, Tefoil, WD 40 and then tried
some heat with the welding torch, enough to get the muffler stub red hot
but didn't want to do any damage to the aluminum engine part. I have
put a pipe wrench on the muffler and pulled, hammered, etc and it will
not budge. Have cut off the main part of the muffler so there is about
1 1/4 inch stub remaining. May have to carefully grind slots into it in
about 4 places where it threads into the engine after cutting it off
flush, before I go to this extent does anyone have any experience with
this type of metal seizing. Sorry for the long post.

I had a brand new lawn mower with a B&S engine that I wanted to
install a mosquito fogger on. Needed to drill and tap the
exhaust pipe. Natural reaction is to unscrew muffler and take it
over to the drill press. No Go. Muffler/pipe would not come
out. Had to use a drill motor and tap in place.

There is something to be said for government by a great aristocracy
which has furnished leaders to the nation in peace and war for generations;
even a democrat like myself must admit this.

But there is absolutely nothing to be said for government by a plutocracy,
for government by men very powerful in certain lines and gifted with the "money touch,"
but with ideals which in their essence are merely those of so many glorified pawnbrokers.
