........good one, Brian....

Yes, it's hard to teach an old dog new tricks. Back in the 70's I had a dear friend
that was flying "carrier" c/l competition with his son at the handle...."Jim" tweaked
the engines (Super tigers)....looked me straight in the eye, and told me that "engines
will idle a lot better with a non idle-bar plug".

This of course went against everything I had "thought I knew" about the aero-model
engines. He explained...."why block the fire from the fuel ?" It made sense to me, I
tried it....and he was right. The regular plugs....having perfect exposure to the fuel
charge....does in fact work better. Try telling that to some died-in the wool idle
bar users, and watch the expression on their faces. They might even call you a liar.

Same thing with engines, like this ring thing. You get these "Internet Jockey's" that
never had a day of formal mechanical training, never worked in a shop for a day
in the lives.....probably never physically held a piston ring in their hand....

....and they want to argue and nitpick about how rings seal on a cylinder wall.

WHEW !!

FBD.
